Good grief, 5000 dollars spent for a music "server" is getting close to the peak of audiophool stupidity (dudes who are largely clueless about anything related to pc hardware).
A basicc synology NAS+Seagate Ironwolf NAS drive should run you about 300 bucks. It should sit isolated and serve your music beautifully to multiple systems around the house. You gotta know where to spend your cash.
Depending on how golden your ears are, spend your money on a good standalone R2R DAC (Denafrips Venus, terminator, etc). DS DACs in 2020 peak out on diminishing returns at 1k. If you spent more than 1k on DS DAC offerings, it is cash down the drain.
When tech companies see the audiophool, i bet they laugh all the way to Chinatown. I recently saw a review for a audiophool "network switch" priced at 1000+ dollars. This is outrageous. I understand that not everyone may have advanced degrees/work experience/exposure in certain tech areas. But, I sincerely hope that some of you guys do some research and attempt to educate yourselves better
