Hi all! I'm new to the forum, but have been reading around and been really enjoying the community, support, and ideas shared. I recently picked up some KEF Q150 bookshelf speakers, receiver, and a Pro-Ject Debut Carbon Esprit SB (DC) turntable (w/ Schiit Mani preamp)—just getting started in the world of hi-fi audio, and have much to learn (but having a lot of fun). However, despite the incredible sound coming from my vinyl collection with my new setup, I've been scheming a way to integrate digital music into my setup. After about a solid month of research and learning, I have a parts list for my planned digital audio PC / music server build. I wanted to share and hear all thoughts / suggestions / concerns before I pull the trigger—it's not the cheapest build (approx. $2650). The main goal is to run either Ubuntu or Windows 10 for a Roon server / Tidal playback on the DAC I'm about to buy—Pro-Ject Pre Box S2 Digital. The other goal of the build was to allow for 4K HDR playback (so 3840x2160 @ 60Hz) as an HTPC. Also, trying to limit the TDP as much as possible and go completely fanless/silent/no moving parts. The PC will live "headless" in my living room next to the stereo equipment. Here it is! CATEGORY COMPONENT MODEL NO.

I just finished this PSU for my CAT. Some figures measured from the AC receptacle (with +/-5% error I suppose) -when PC is off (in standby mode): 20W -when PC just starts (where the peak comes): 90W -when PC running smooth after boot up: 70W The circuit design refers to this: Linear ATX power supply - diyAudio with some change of regulators (I use LT1083 for every voltages, and dual 12V rails), basically they are the same thing just more capacity.
