I've dealt with the whole noise issue with the purchase of a secondary rig that fits into one of the shelves of my desk. Not having much in the way of capital to use and tired of the drone of my regular rig (which it just wasn't practical to try to silence--it's already fairly quiet just not silent when you don't want any other sounds during concentrated listening) about a year ago I got one of those Beelink M1 mini-PC's w/a Celeron N3450 and 8Gb RAM Win10 Home. It is utterly silent w/no fans although I've added a very quiet AC Infinity Multi Fan SP-3 that sits underneath it and can be switched on when the CPU temps start getting up into the 60's. They claim noise of 18 dBA--and real world when you're sitting at the desk, as it's on a shelf sort of at the back, it's just a barely audible, unobtrusive whoosh).
The Beelink is certainly not as robust as my main Core i7 rig but, running Audirvana Plus for Win10 and employing lots of USB connections and a 4-port hub, it performs pretty well and the utter silence that it runs at makes up for any performance/speed issues, mostly when trying to open up too many apps. The 8Gb RAM really helps with a lower performance CPU but it runs Audivana, Tidal, Spotify just fine.
I've got the ability to connect a nano iDSD Black Label (main DAC), Meridian Explorer2, FiiO Q1Mk2 and Schiit Modi2U/Magni2U into its USB chain and it's surprising how versatile the set up is. All on the cheap for the most part. Although it isn't much to look at it's got lots of utility, pretty good sound and can be run either dead silent or near silent.
