Building an AUDIOPHILE friendly PC from scratch so what is a must to consider in 2020?


First thing-I realize there are computer audio web sites out there, but I would really like to know what the wise members of AGON have done or would do when looking at ensuring a QUIET PC can coexist when playing music in a mixed use office/listening room. Current Windows 7 desktop serves as my central ROON location. It directs audio sources( mostly streamed via TIDAL and RADIO PARADISE) to my system. I switch between an ALLO USbridge that runs USB to an MHDT Orchid DAC ("NOS tube days") or a CARY DMS-500 streamer/DAC ("DSD, Over-sample days"). Despite the problems it can add, I even on occasion use TIDAL's own PC based player. Regardless, the PC is always on doing something!
SO.... when seeking to maintain signal integrity AND limiting PC generated noise in my room ......are there some absolutes to consider when building from scratch? ( type of hard drive/SSD, power supply, pc case, cooling fan, network switch or specific style or brand to use of any?) KEEP IN MIND- I am not only looking to limit the corruption of any audio involving my PC but I also am really looking to LIMIT the NOISE the actual PC makes when I am trying to just listen to music while working !  Has anyone out there had any luck?
(***I realize Ipad, Iphone, can control everything via WiFi but my situation requires a desk top PC)  Thanks!

Depends on what other thing you are planning to do with the computer and what you want to spend. If you use USB to connect  to your dac consider something like a femto USB card they are expensive. For hard drives PCIe instead  of sata easier on the CPU. There are some fanless cases but if you use fans use large as you can get in the case. Get the best CPU with the most cores you can afford , most memory you can afford, won't tax the computer as much and will run cooler and quiter. 
M.2 drives are now cheaper than sata as well as faster.

You mentioned Audiophile computer which is why I suggested the Jcat femto USB card but it’s about $500 I wasn’t sure if you were putting it close to your USB dac.
