If you have enough Panzerholz left, about the size of your case, you could build an isolation platform for the server à la Taiko Daiza, also with 3 extra tiny Panzerholz feet. Users rave about them. If you want to go all the way you could make 3 copper disks to go between the feet and the platform and CNC a spiral shape in the bottom ;-). https://taikoaudio.com/taiko-2020/product/daiza-isolation-platform/ Yes, I do have enough left and made one, but without the routed spiral....yet. Currently the server is sitting on it. Next I'm going to try it under my turntable. Audio System Link to comment

I like how Taiko put copper discs and foam inserts to further optimize isolation (beside the beautiful spirals of course). Also the little Panzerholz feet with foam inserts are well thought and essential according to Emile. He put 3 under the server and 3 under each platform, I will try make those too. And I wish I could but no routing though! Link to comment

Best to stick with either real fiber optic or straight RJ45 copper ports. Probably best not to take things out of context. The new switch and NIC from Taiko are designed around a Direct Attach Cable and per Taiko the Passive version of the Direct Attach Cable is "dramatically better then any RJ45 terminated UTP or STP cable". (source link) Taiko explains why in this post: https://whatsbestforum.com/threads/taiko-audio-sgm-extreme-the-crème-de-la-crème.27433/post-838675 That does not mean that the Direct Attach Cable is better anywhere else. Taiko has taken advantage of this cable design in their switch/NIC design. I agree with some of the comments @Superdad made above. If you are running a 1Gbps network, you are probably better off sticking to RJ45. However, if you are running 10G or 25G or 40G or 100G network, I would stay away from RJ45 (it's not even an option for some of these standards). I have done very little experiments with higher speeds and the main reason is that most of the 10G and 25G NICs I have tried generate a lot of heat and are not suitable for a passively cooled server. Even a couple of degrees higher temperature inside my computer chassis has always been audible and impacted negatively the sound quality. And while I have tens of thousands (literally) of high speed NICs at my disposal at my full time job, I've always had the same experience when I tried one in my passively cooled server. The first reaction when I boot the server with the 10/25G NIC was always "WOW, this sounds so good". 30-40 minutes later, the reaction was always "meh, not as good as I thought". It took me a while to realize why, but at some point it became obvious. As the NIC was running and radiating heat inside the chassis, it raised the temperature inside my computer, and that easily ruins the sound quality. However, if I was running a 10/25G NIC, I would seriously consider trying AOC cables. drjimwillie, MarkusBarkus, happybob and 1 other 1 3 Industry disclosure: https://chicagohifi.com Dealer for: Taiko Audio, Conrad Johnson, Audio Mirror, and Sean Jacobs Link to comment

Sorry, but despite the moniker of “passive”—versus the longer distance “active” versions—there is nothing passive about those Direct Attach Cable transceivers that stick into an SFP+ or QSFP cage. They contain—at minimum—an RGMII to SGMII PHY transceiver chip, a 50-cent clock, a set of magnetics, and cheap power supply voltage regulators. All crammed onto a tiny board and all powered by the same 3.3V feed to the cage. So while power consumption of whatever cable they chose may be low, the noise and embedded low-frequency phase-noise/jitter performance is not going to be great. By comparison, an optical SFP/SFP+/QSFP transceiver is a much more “passive” device in that its fiber to dual or quad differential pair transceiver chip runs free of any clock—direct into whatever silicon is receiving it, where it then is clocked. [I state it this way because the output of a fiber optic SFP transceiver is not inherently Ethernet or any particular protocol. Sure it generally is fed to an Ethernet switch chip/MAC processor’s SGMII/QSGMII port, but those lovely differential pairs could just as easily be carrying data bound for some other protocol. (USB3.0 SuperSpeed being an example as it two differential pairs—one for each direction—matching nicely with SFP+ transceivers.)] kennyb123, Johnnydev, StreamFidelity and 2 others 2 3 UpTone Audio LLC Link to comment

It will likely partially undo the benefits of the Panzerholz. PH is excellent for removing vibration from inside the component by absorption. The short version: PH does not ‘move’ like rubber hence the benefits for (pitch) perfect sound. A small hard surface for footers is recommended. (But no spike). Note the small outer edge contact surface and the foam inserts that fill the air gap. The foam is sticking out a little and will be compressed under components weight for optimal result. Dimensions of this footer are very strict, changing height or diameter will change the effect. This is what Emile explained on WBF. Quote You need something rigidly coupling equipment to platform, so not an “isolator”. Otherwise they would partially interfere with draining mechanical energy from the appliance. Just trying to “isolate” the appliance from the floor is a quite limited approach. We also, in fact even more so, want to drain mechanical energy generated inside the equipment and applied energy from soundwaves hitting it. https://www.whatsbestforum.com/threads/taiko-audio-daiza-platforms.28666/post-589695 Link to comment

To ship a whole panel to a residential address, the carrier charges extra fees of US$150 on top of the freight costs. Sometimes our residential customers will pick up at the local carrier’s terminal to avoid these residential delivery fees. Alternatively we could cut the panel in half (our cutting charge for 1 cut is US$30) and ship 2 packages using UPS. If you are interested to proceed with one of the above panel sizes, we could investigate the shipping possibilities and costs for you. Jeremy Anderson 1 Audio System Link to comment

But I liked very much the image of a pallet traveling with this precious and heavy material all the way from the north to you after first sourcing it of course. Still... I think it shows how motivated you were. Like me, I guess. It seems a fascinating material with an interesting history. I mean using bullet proof wood (!) invented in the 1940's, to absorb acoustic energy in 2020's. (and allready speakers and footers where built with it before that.) Because of the German name I started looking in Germany then Europe, crossed the ocean to the the US and then realized the company was located almost next door to Ottawa. They would cut me a 1/4 sheet (3 platforms) for an affordable price. Most interesting part I read on WBF how Emile did his research in PH sheets combined with copper discs and the exact dimensions for footers and more very precise details like air gaps filled with foam to avoid oscillations, also tiny holes in the platform and discs and the CNC cut shape. I hope it works out well for you! Link to comment

The other day I installed Panzerolz wood to the Taiko DIY case, then moved the PSU components into the case. This was @Nenon's unregulated supply that he graciously sold me after a little begging on my part. All supply components, including cables were his. We went in on some Panzerholz and I have a little left if anyone lives in the Chicago area and is interested. It would need to be cut which will involve access to a table saw and some time. The wood isn't terribly difficult to cut using a new blade. I did break 2 drill bits and 2 screws inside the wood when preparing to install the components. Everything is screwed down tightly and doing this into the wood as opposed to the case itself made things fairly easy. Does the Panzerholz have any impact on SQ, I don't know. Too much time passed between listening to the supply in its previous case to it installed on the Panzerholz. I hope that it does. The Taiko board between the transformer and the caps is free floating. I could screw it into the case but didn't see a need. Cables are from Ghent. Neotech UPOCC in JSSG 360. RAM is from Taiko. Some Apacer stock they had laying around. Optane and Asus m2 to PCI adapter with Intel m2 cards are all the same models as Taiko uses. I've added 3M RF shielding to certain parts of the case. There are some small improvements I can make and will over time. I need to clean things up a bit as these pics were taken just after installing everything. This build replaces the SOtM modified motherboard I had been using for several years with much enjoyment. That server still sounds fantastic. I used Nenon's PSU to power it for a while and it pushed it to a level I never expected, which is why I asked to buy his supply, knowing he had recently acquired the Extreme. Right now I'm battling an issue upsampling to PCM 1536. When using Euphony or Audiolinux with a JCAT USB XE it comes out distorted. PCM 768 is fine but doesn't sound as good as 1536 direct from the board's USB or to an HQP NAA. As a result, I'm leaning toward the continued use of an NAA as my preferred best sound. The NUC NAA is tapped to a SOtM sCLK along with the SOtM switch and tX-USBUltra. The tX-USBUltra helps in all counts. I can provide more detailed listening experiences of the different scenarios another time. /cdn-cgi/mirage/068727e2929ec2a60cd8e8d0538a9295fc5337848e58bdc42e28b4c431363ca6/1280/https://audiophilestyle.com/uploads/monthly_2022_12/image.thumb.jpeg.666f674c3e3a199ff53565da657ad94d.jpeg /cdn-cgi/mirage/068727e2929ec2a60cd8e8d0538a9295fc5337848e58bdc42e28b4c431363ca6/1280/https://audiophilestyle.com/uploads/monthly_2022_12/image.thumb.jpeg.39c6dea9ded8cc20fb393603903cbd0c.jpeg /cdn-cgi/mirage/068727e2929ec2a60cd8e8d0538a9295fc5337848e58bdc42e28b4c431363ca6/1280/https://audiophilestyle.com/uploads/monthly_2022_12/Three.thumb.jpg.debe8b7e2d5e6fa874aa37c057cbcc8c.jpg /cdn-cgi/mirage/068727e2929ec2a60cd8e8d0538a9295fc5337848e58bdc42e28b4c431363ca6/1280/https://audiophilestyle.com/uploads/monthly_2022_12/Four.thumb.jpg.d6f1868d25d903da783b8fbdd4096252.jpg Very nice.

First of all you seem to struggle with space inside the case and there also needs to be air circulating to avoid too high temperatures. Further I would think a small piece of PH simply will not have the capacity to absorb much acoustic energy, if that is what you try to accomplish (but it looks great though). If you look for isolation from acoustic vibration, very likely it would have an audible effect if you: 1) make sure all inside the case is well attached but never overtight to avoid damage to electronic boards 2) install a large and thick piece PH (platform) under the case making sure there are three or four hard contact points, between the server case and the platform and also between platform and rack/floor. If you are looking to protect from Electromagnetic interference (EMI) better options are relatively thick copper or aluminum walls and mounting plates (flatbar) that will also take up less space. Just a thought. flkin 1 Link to comment

I may drill more holes in the side and top of the case to allow for heat dissipation. It does not get too hot inside its cage now. While copper might be ideal or at least it looks nicer, I know this works. I've used it in my last server build and for other components. I've heard the improvement. There are varying thicknesses.
