Starting from scratch: NAS, PC, etc???

[yugnat]

I'm on the list for the new MicroRendu (renderer) from Sonore and I'd like to get a new rig to run Minimserver. I'm after the best sound quality, I don't expect there to be huge differences but I'd really like to hear recommendations from the forum. My music library can fit on one large drive. Should I go with a two bay / single bay NAS or PC? I'm willing to go with a Synology DS716+. I'm also willing to build a new PC, either high power or low power. Then there are the NUC's, mini pc's, mac mini's, and Raspberry Pi's of the world. What would be the best rig for a dedicated Minimserver system? If not a 'best' then what is your preferred? Thanks!
