    So are you afraid of ESD? Does the thought of Arctic Silver Heatsink Paste make you go cold? Are you fearful of Phillips screwdrivers? Do you still want to play with the NUC? I have found the Goldilocks computer for you. Semi-Custom Fan-less NUC using the Dawson Canyon boards, we have come to love! Orderable with Optane SSD and much more. The system is fully warranted and you can extend the warranty. You can order it with our without an OS installed. (At least get Ubuntu installed for backup and order a USB stick from them) Simply NUC has a custom build that is perfect: https://simplynuc.com. At the top of the page see the custom NUC button. Click that and scroll down to the Fanless case section and pick the i7 model. The options I have selected above are "perfect" for a NUC to run Roon Server, etc. Get Ubuntu installed so the machine has something to run when you start up. The PORCOOLPINE comes with a power supply so you can get going right away. I purchased my Dawson Canyon board from them so I am only a happy customer. I was going to have a model of these custom built for resale, but there was not enough interest and my budget would not allow speculation. You can get an upgraded power supply at some point. You can order any of the options you would like. I just did an Euphony OS setup post that you can follow or you can setup Audio Linux from my NUC build post: HAVE FUN Bob Here is an interesting review of the PORCOOLPINE from another site: https://techsterweb.com/2019/01/27/porcoolpine/
  2. I have been using Audiolinux in a custom built DIY server and NUC endpoint. Headless AudioLinux is getting more and more user-friendly and Piero provides great support. For $100 (two copies) in software licenses, it is a considerable value. I can custom setup the BIOS and tune the OS. This project is fun if you enjoy playing at that level. About a week ago I found Euphony. It is also based on Arch Linux and appears to provide some of the same value as AudioLinux. There are more features in their OS as it has Music player software and some other flourishes. I am a Roon user, and I do not currently intend on changing that! I intend to try their player software at some point. I am going to add a small (250GB) NVMe M.2 drive to the server and dual boot between AL and Euphony because I have it and there seems to be a shortage of Optane sticks this week. One of the first items to note is that Euphony does not use ACPI boot you have to turn legacy back on if you were using AudioLinux. Euphony basic setup is relatively simple. Download the image and install it on a USB stick with Etcher on the MAC or their Windows installer. For Euphony to run you need to register it for a trial. There is an odd back and forth setup between the website and the program, but you get an email with the trial key pretty quickly. Then things get weird. Unless you purchase a license for $289.00 you cannot install the system anywhere. You have to run off of the USB stick. This is not conducive to running Roon Core. I am sitting here springing forward and sleeping on going any further. Bob
  3. We are trying a new wiki-esque method of showing the settings in AudioLinux. Notes as of 6/25/19 The Dawson Canyon NUC also know as the DNHE / DNKE / DNBE / DNFE system is classified as a commercial grade NUC with a 3yr life cycle. The dnh"E" stands for Extended Life. Most Intel NUC(s) have a refresh cycle of about 18 months to two years. However, anytime Intel releases a commercial grade system to the market, the life cycle is a minimum of 3yrs. According to the roadmap, the Dawson Canyon will continue to be on the market all of 2019 and 2020. Currently, we are dealing with an Intel shortage that should come to rest by the end of July. The NUC(s) impacted are mostly i7 and i3 Dawsons (in all formats H/K/B/F. At the root of the following thread you will find the beginning: If this construction system is too much for you to do, or you want to buy rather than build. Here is one option: I have started a thread on building a music server. See below: There has been a HUGE flurry of activity on the “Massive SQ” thread onAudiophileStyle. The discovery of putting a specific Intel NUC computer into the stereo system as the network endpoint running Audiolinux (AL) in RAM with no other disks has dramatically improved the audio quality for many of us. Here is a link to where the NUC part of this thread “started:” https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/?page=359&tab=comments#comment-860030 Two primary NUC models are in use. The single board computers are typically put into a fan-less case, hooked up to a high-quality power supply, booted off of a USB stick into RAM. What I hope to accomplish here is to have a “recipe” for success. Just like baking a cake you need to have your tools and ingredients ready before you start. Remember this is first and foremost a DIY project and t is also a “Work In Progress”. For me, it is also a rousing success. From 0 to NUC/AL/RAM in 2 hours *Not including Prep* To bake our NUC cake, we need the following components and tools. Setup Tools USB Keyboard and Mouse HDMI Monitor and HDMI cable Power supply for the NUC. **** discussion on this later *** Small Phillips screwdriver Anti-static work strap. A well-lit place to work A Windows PC or Mac to download AL and set up the USB stick Internet connection Just the right amount of coffee What needs to be in your Stereo system Ethernet connection A USB cable to the DAC Power supply for the NUC/AL Roon system (my choice, there are others) What you need to buy Two NUC models have been popular in this project. From all reports, they both sound great. According to some the i7 model sounds better and costs more! Take the time to read the relevant parts of the “massive” thread. I chose to get the Core i7 model. Note that the prices are estimates for the USA and do not include tax, shipping, etc. The Celeron Model comes from Intel as a complete system in a box. You need to extract the computer from the box and mount it in the fan-less case. Intel NUC7i7DBNE single board computer. $575 Akasa NUC Plato X7D case $170 OR Intel NUC7CJYH. $130 Akasa Newton JC Fan-less. $100. https://amzn.to/2Wvd7fg Here is the rest of what you need to order: RAM Ballistix Sport LT 8GB Single DDR4 2400. $60. https://amzn.to/2WsAPZr USB Stick. SanDisk Ultra Flair 32GB USB 3. $10 Audio-Linux headless. $49. (license and one year support) Once you order up the parts and get everything in place, let us get Audiolinux setup installed on the USB stick. You can do this from Windows PC or a Mac. I have done both following the instructions on the audio-linux.com website and if you have a PC do it there for speed. The Mac method took 75min to build the same USB stick. *** Etcher does run on MacOS. You should be able to build the USB stick there. *** In your favorite Windows PC web browser download your Linux image and a copy of Etcher. http://audio-linux.com https://www.balena.io/etcher/ Put the USB stick in your machine. Install and run Etcher. Etcher prompts you for the location of the image file you want to flash to your USB stick. Etcher should show the target as your USB drive! MAKE Sure because it ERASES the target! It takes 10-15 minutes to complete flashing the USB stick. While the USB stick is flashing, we can build the NUC board into the case. For the rest of this setup, you need a nice clean workspace and your anti-static strap. Oh and go slow on the Coffee! First, unbox the case remove the top cover to inspect the inside and inventory all of the materials. The top case cover has four small Phillips head screws to remove. Here are three views inside the case. The above views are the inside front with the board holding the power switch, the LEDs and the two USB 3 ports. The small board is the two front USB 2 ports. Below is the inside rearview where the computer board is mounted and the shielded cutouts for the ports. Flip the case over and put the feet on so that to protect the bottom from scratches. There are four feet with screws to attach. Be sure to put them in the correct screw holes. You can now carefully set aside the case as we have to do a “fan-ectomy” on the NUC Board. You are dealing a bare computer motherboard; please observe standard anti-static protection procedures. An anti-static wrist strap and the anti-static bag that the board comes in are your friends. Here are pictures of both sides of the board. On the top side, you have the RAM and M.2 slots and some of the other connections for drives. The second picture shows the included fan and heatsink that we have to remove. First, you need to unplug the fan power cable. The connector is small so be careful pulling it off. Remove two small screws holding the fan down to the heatsink. The heatsink is attached to the motherboard with three screws. In the above picture, you can see them on the silver bar and in the recessed hole in the black part of the heatsink. Carefully remove the screws, and you can pull the heatsink away from the board. Note that the heatsink “grease” sticks them together a bit. Below you can see the separated heatsink and the board with the compound on the CPU (black part). Now you need to clean up the old heatsink compound from the CPU. Use cotton swabs and some alcohol to clean it off. The picture below shows the CPU module after cleanup. Next put the new heatsink grease on the CPU and the heatsink pad on the smaller black rectangle. The pad is a bit fussy to get stuck down. There are some pictures in the install page from Akasa that may help. In my case, they have an addendum showing how they now include the heatsink grease. From the picture below I used too much thermal paste! Thanks, @Dutch for pointing that out. A couple of dots would have been enough Here is a video of better ways. https://www.youtube.com/watch?v=JYwHB2P6GmM It is time to install the board in the case. Carefully set the motherboard on the static bag aside and bring the case back to your workplace. Put the rear of the case closest to you and move the cables out of the way. Observe the part of the case where the CPU seats on the upraised heatsink and the four standoffs for mounting the board. There are four screws and fiber washers to hold the case in place. Carefully set the board CPU side down onto the case aligning it to the standoffs. Being careful not to strip the screws install them all but do not tighten. Once all four screws are in carefully tighten them down. I do them: upper left, lower right, lower left, upper right. Just my method! Next, it is time to connect the cables. The two USB 2 connectors are on the upper left, and the black thin flat ribbon cables plug into them. The two big USB 3 cables plug into the USB connectors on the top. Finally, the multi-color cable plugs into the header. The connector is keyed and goes on the leftmost pins. There is a hole blocked on the connector and a clipped pin on the board. With the connections completed installing the RAM in the bottom slot is next. The bottom slot is slot #2, but folks think it is the right place. The little RAM board goes in at an angle into the connector and is then pressed down to hook into the spring latches on the side. Dress the cables so that you can screw the top plate back on to the case! The “hardware” part complete. Now for the “smoke test.” You need to connect the keyboard, display, mouse, network. Finally, plug in the power cable and press the power switch to turn on the computer. ** do not plug the USB stick in yet ** Making the initial changes to the BIOS If the NUC passed the smoke test, the computer boots up to the BIOS where you have to make some settings changes. Note that on the first screen the UFEI Boot selection is ticked on. Note the temperatures of the CPU. Keep an eye on them as we go forward to make sure you did a good job on the heatsink grease! Mine here is under 30C which is GREAT. Set the BIOS clock on this screen if it is not right. Select the “Advanced” menu selection shown on the above screen to go to the next settings pages. Select the SATA tab and turn off SATA and the activity light. On the Boot Configuration page, I have mine set to boot USB first, Network last and the USB, and Optical are checked on. (may be able to uncheck the Optical). I may be doing a network boot, so I left it alone. On the Secure Boot tab, uncheck the Secure Boot item to disable it. Audioliniux does not use Secure Boot. On the performance tab under Processor, uncheck Hyper-Threading and Turbo Boost. The only other change I have made is to set the Primary Power setting to Balanced Enabled. I think others have set to Low Power. ** Note that this is all still a bit of an experiment and these settings may change. ** Insert your Audiolinux USB stick into one of the USB 3 connectors. You can now use the F10 key to save and exit the BIOS. Audiolinux Setup We are now on the final leg of the setup. With great thanks to Piero Olmeda, the author of Audiolinux distribution this part this part is pretty simple! When the machine boots up, some text goes by and if all is well the computer displays the Audiolinux menu screen. You may see a few differences in this screen depending upon what version of the system menu you have installed. Piero updates the different parts of the OS on a regular basis. Before we start with the configuration, you should update the system. This menu is driven merely by the cursor keys, and the enter key. So cursor down to the update menu and press enter. Since you are not getting ahead of me yet, you are booting and running off of the USB stick, so no RAM mode issues need to be addressed. Note that I am running this NUC as a Roon endpoint so I have not explored other audio packages. During the install steps, you need the default passwords for Audiolinux. I assume that they might change so, please refer to the Audio-Linux.com website to find them. (scroll down and look or search on the page for the correct passwords. Cursor down and select the update menu item. You need to run the first four updates if you are following along with me. I did them in order. (I do not know if that order is “correct”). You will need your passwords during this. After you have completed the last update of the Audiolinux menu go back to the first page and select option 8 Console Mode. That takes you to the command line. DON’T PANIC! Just type in the command: menuand press enter. You have restarted the Audiolinux menu, so the new version runs. You are now going to configure the system to be a Roon endpoint, run in RAM and extreme mode. From the first screen select the configuration menu item. The above screen appears. Select the Roonbridge men item to set-up endpoint. After that completes set number 14 (scroll down) Set real-time priority to “extreme." Finally, select 15 enable ramroot. Select Cancel to return to the main menu screen and select Reboot. The computer reboots and automatically loads the OS into RAM. As the machine boots up and pauses for a few seconds displaying this screen. It will automatically start-up in RAM after that delay. After the boot to RAM is complete, the Audiolinux menu appears. From the Audiolinux menu check the CPU temperature found on the “Status” page. Also check the Audio Status from the “Configuration” Page. HURRAY! Pat yourself on the back. Toast yourself! Your Audiolinux Roon endpoint should be fully operational. Grab a USB cable and DAC and hook them up. Fire up the Roon application to add the new device to your audio system. There are some more steps to perform, but for testing purposes, you can run the system right now to see how it works. I mentioned at the start of this article that a good power supply is beneficial for NUC to produce the best sound. The NUC runs from 12v to 19v DC. There are reports that running at 19V may sound better. Some of the users have the UpTone Audio LPS 1.2 running their Celeron NUCs. Others are using Paul Haynes supplies, and I am sure there are many others. I have an UpTone Audio JS-2 in my system, and it runs my NUC and my ISORegen. Before you put the NUC into production, there are some other settings that you need to do. I am a huge fan of having the clocks running correctly in my computers and setting up Audiolinux to use network time server to keep the clocks on the beat is essential. Some other items can be adjusted as needed. @austinpop has an excellent post describing how to do some of them. https://audiophilestyle.com/forums/topic/54933-audiolinux-and-nuc-troubleshooting-and-tuning/?tab=comments#comment-901393 This little bit of cleanup work requires you to edit a couple of files and run a few commands on the command line in Linux. Now is also the time where you can do some of the fine-tuning and changes that may influence audio quality. I am not going to show the final tweaks of Audiolinux in this article. I want you to play, listen, and read some more. There is another thread on tuning and troubleshooting. https://audiophilestyle.com/forums/topic/54933-audiolinux-and-nuc-troubleshooting-and-tuning/?tab=comments#comment-901393 **** IF you are going to have more than one AudioLinux device running Roon on your network you will most likely run into a problem where Roon gets confused about devices. You will have to apply the fix in this post: https://audiophilestyle.com/forums/topic/54933-audiolinux-and-nuc-troubleshooting-and-tuning/?page=31&tab=comments#comment-918823 I am planning to post a summary of my settings over the next couple of weeks, and I have the time/date setup and fine-tuning in that. *** I am close on this one please stand by**** This article is a summary of my NUC build and a record for my own memory. I hope that others find value in it. There is so much work that has been done by others I cannot thank them all. I have to shout out to the following folks for all their work. @austinpop @lmitche @romaz @greenleo @hifi25nl @rickca I know that there are so many others I cannot remember them All! Thanks Bob Fairbairn ---------------------------------------------------------------- Adding WiFi to the build I have been thinking about adding a WiFi card to the build so I dug around and found the card and antennas on Amazon. So here is ONE WAY to add WiFi to the NUC Parts needed M.2 card for your NUC. In my case the Intel AC-8265. https://amzn.to/2Wt9mH2 Antennas and cables for the card. https://amzn.to/2Bcm5Vx Tools needed Phillips screwdrivers as before Needle nose pliers. 5/16 in socket wrench Small round file You might want to skip the coffee before you do this. Do not forget your anti-static protection ! This is the point where I have to play the robot on "Lost in Space". DANGER WILL ROBINSON The connectors on this card are tiny, fragile, and fussy. In my build, the Akasa case is anodized black and I could not insert the SMA connectors into the case without filing the holes out a bit. NOTE metal filings are conductive and can short out the CPU board. I HIGHLY INSIST that you remove the board and then file the case. HIGHLY INSIST! Here we go This is where the board will go and you can see the rubber grommet for one of the antenna leads. Note that the M.2 board mounting screw has a post below it that has to be removed to put the lower board in. Remove the screw and the post. Here is a view of the socket and the post with the board not installed. The second picture shows the board installed. I had to remove the board to install the antennas leads. *** DO NOT INSTALL THE BOARD BEFORE CONNECTING THE ANTENNA LEADS AND PUTTING THE SMA CONNECTORS ON THE CASE *** Here is the board with the antenna leads connected. It is really close quarters in there. Those connectors are fussy. This shows one of the antenna SMA connectors mounted in the case. I used a 5/16in nut driver to snug up the SMA to the case. The antenna is threaded on and you do not want a loose connector/cable. Finally, the case buttoned up antennas installed. I set up on the bench with keyboard, mouse, and monitor. I can then attach my Chord Mojo for quick test final test and initial audio quality review. Software and BIOS Setup for WiFi There is one BIOS change needed to enable the M.2 card in the machine. Look at the PCI page in Advanced Settings. The WiFi setup is now in the Audio Linux menu! And of course in operation. Foot notes after a few weeks in operation. 1. I have now re-connected the WiFi card as my new home network allows me to create multiple networks. I created a 5GHZ only network SSID for the endpoint. I have that running. I will report further. 2. I am having a very hard time determining if I can hear the difference of the USB stick in or out. I have made some other changes in the network since then and I will go back and re-test.
  4. Update April 2019 There are a few changes in the server that are important. First, I have moved to Euphony OS to run the Roon server software. Next I removed the USB storage drive and am pulling from a NAS for the music. The third change was to change the power supply. I removed the DC-ATX converter and replaced the HDPLEX200 with the HDPLEX400. February 2019 I have built a custom music server to run Roon Core. BECAUSE! I have a perfectly good server or rather a GREAT one from Small Green Computer. Andrew makes excellent hardware, and the OS in the machine is stable and supports a lot of music player software. It is "Plug and Play” and very well supported. It does not lend itself to tinkering! I want to listen and tinker with some different ideas with, setup, power, networking, and connectivity. Thus my build. Just like my build of the NUC endpoint, I am doing this build in public so that others can duplicate it or follow along. A Side Note: John Darko put up a very timely video. It is ostensibly a review of sparkling water and the Innuos ZEN MK3. John speaks the way I think. This is not hard if you have “The Knack.” And No Soldering iron required! General Goals: Roon Core Server Audiolinux OS "Swap-able" components, MB, CPU, Power I want this build to sound GREAT Key design features: Multiple network interfaces for bridging and more No WiFi High TDP capable Xeon, ECC RAM, Optane Storage Option for mass storage Fan-less Powered by an outboard LPS PCIe expansion card with SFP for network testing System Description A dedicated silent workstation / small business class server. The case is fan-less, with an external power supply. There is 16GB of ECC RAM and a 32GB Optane SSD for boot, and database storage. There are two onboard network interfaces which are different Intel generations. I have a PCIe network interface card with a single SFP slot to be the optical network bridge to the "best" endpoint that I will be testing with later. The motherboard supports either Xeon or 8th Generation core Intel processors in the LGA1151 socket. The chipset is VPRO and thus supports Optane storage. The board also supports both ECC and non-ECC RAM with four slots. I am using the entry-level E-Series Xeon E-2124G processor to start with as the price and availability are good. The E-2124G has a TDP of 71 which is well within the case specs. I am using ECC RAM that has been validated to work with the motherboard. Music storage is an interesting problem. I read through the threads on AS about data storage and to be honest, without some summary there is too much data to compile into a “best practice.” In my testing with a different NAS and a different server than I am running now, the NAS did not sound “as good.” I do not want the drive inside the server, as indications are that internal storage degrades sound quality. From the reading on AS an external drive on a USB 3.0 port powered by a separate LPS appears to have partial consensus. I used a simple drive case with USB to SATA and one of the legs of my HDPLEX200 for power. I have a “fancy” iFi Mercury 3.0 USB cable for the data connection. The Case for the Case! I have been researching this for several months, and I picked the HDPLEX case due to the flexibility of their design. The H5 case fits up to a full ATX motherboard like I am using. The H5 case can also support adding a graphics card to your build which I am not using. There is room for both 2.5in and 3.5in storage devices. The H5 case is designed to support alternative power supply configurations which is one of the bigger keys to performance. Here are three ideas for power: Install an internal AC/DC + HDPLEX DC to ATX Install the internal DC to ATX with an external LPS Adapt external LPS to ATX wiring I would suggest that you download the manual from the HDPLEX website and study it while you are waiting for delivery. There are a few tricky bits and lots of screws. Buying "stuff." Picking suppliers is a problem today. Many online stores are marketplaces with other vendors inside of them, and that adds risk to the purchase process. I purchased most of the server computer components from Newegg.com. The Power supplies and case came directly from HDPLEX. I want to thank Larry at HDPLEX for helping me validate the fit of my motherboard selection during the pre-purchase process. Great customer service there! I purchased these from Newegg $248 ASUS WS C246 Pro Motherboard $250 Intel Xeon E-2124G $214 Two Kensington 8GB ECC RAM (check MB validated models) $144 PCIe FMC network card. (optional) I purchased this from Amazon. $62 Intel 32GB Optane M.2 SSD From HDPLEX I purchased the following items: $485 HDPLEX200 LPS $388 2nd Gen H5 Case with 400W DC to ATX internal supply Finally purchased from my local MicroCenter: $225 Seagate 8TB Barracuda driver (5400 RPM) $40 VANTEC NexStar 3.5in Drive case. (USB 3.0 and eSATA) Total of $ 2056. I will not count research time as that is endless. Actual construction and setup were completed over two days. I estimate about 10 hours of review, assembly, software configuration, and BIOS learning. As a reminder, I do this stuff for FUN. If this sounds like work, please buy a commercial server you will be happier! ———— BIOS Setup I have turned off all the fan controls and monitoring. The fancy signed secure boot had to be turned off. I have NOT changed any of the default CPU settings. I have not turned off all of the “other” hardware that I will not be using. I had some issues with the boot order. I have not found the way to boot off of USB first every time. (I will try to do BIOS screenshots later) ———— AudioLinux Setup Using Etcher, I built a USB stick with the 1.0 release of Audiolinux headless to set up the server. For Roon Core setup I had the configuration for the Optane boot/storage split and the USB drive for music. For the initial testing, I am running off of the Optane. *** See the AS thread about Audiolinux software configuration. I have edited the thread starter with the setup for the server. There is more detail to add as it is in outline form for now. *** After all is working I will shift over to running in RAM. I setup bridging using the AL menu. The server is connected via Ethernet to the rest of the home network and via Fiber to the TLS Switch and the NUC endpoint in the stereo. ————— Build Process I am an experienced PC builder, and they usually go together pretty quickly. This build took a bit longer than I expected. Taking great care with the heatsink, the heat-pipes, as well as the first time is this kind of case slowed me down. If I built a second one I could do it in half a day. Please remember to use proper anti-static protection. Do not over-use heat-sink compound! And have fun! Let's get started! Here are the "goodies" to start building the case This is the heatsink system A little out of context! This is a single Motherboard stud. You have to place them properly for your board. Next we put the posts and the power switch button on the side panel and mount the PCB for the USB ports, etc. Here is the side panel mounted to the base and you can see the motherboard standoffs already inserted. Now it is time to start on the CPU heatsink On the LGA11551 socket, the pins for the CPU are on the motherboard. CAREFULLY place the CPU on the socket and close the locking cover and bar. I did not take a picture of the underside of the motherboard where the bottom part of the headsink system attaches. The casemanul covers this pretty well Add the heatsink compound to the base of the copper heatsink Here is the base of the heatsink attached to the motherboard Another view of the case with the side panel, MB and heatsink ready for the heat pipes. The manual covers the intall of the heatpipes well. Again donot over use heatsink compound and proceed slowly. Here are some shots of the system installed and hooked up You can see the RAM and the Optane drive installed here. The DC to ATX power supply is to the right here. I completed the BIOS settings outlined above and installed Audiolinux. The server is running bridged to my NUC. I have Roon running and the Music source is on my NAS. As I am publishing this I am copying the music to the external drive that will be attached to the server. 3.44TB takes a long time to move over USB 3.0. I need to round out the documentation of the BIOS setup and the Audiolinux software setup. I have done very little listening at this time. I do have a smile on my face so far!. The server should be in production mode by Sunday. I will be adding more pictures of the completed system and reporting on the sound differences I am hearing. I would like to close this with a should out to lots of folks on Audiophile Style who have been sharing their work with others. Bob Starting the "postscript". Here are the completed pictures of the system still on my messy workbench. Here is the disk drive enclosure with the 8TB drive inside for music storage. This is the other side of the case. I hate how black things collect dust and stuff. Here you can see the HDPLEX 200 sitting on top of the Sonic Transporter i7 DSP. The case it is in appears to be the baby brother of the H5! Note that I have the power supply plugged into a Transparent Audio Powerbank 2. I have not used the HP power cord on the bench. I will set that up before I really get into audio testing. The next upgrade happened today. I purchased the HDPLEX 400 power supply and here are the changes to the server to remove the DC-ATX converter and connect the new supply. I disconnected the DC-ATX converter and removed it from the case. (sorry no picture) First the old 19V socket and mount have to be removed to place the back to back ATX boards. This really requires you to remove the back panel first. There are four studs installed and the board pair is screwed into the back plate. Then the two internal cables are run from the connector board to the Motherboard. The two longer cables are connected to the outside of the case and run to the back of the HDPLEX supply.
