Suggestions on Better Server Setup than Mac Mini


I'm using a Mac Mini as my server, with Audnirvana and external Ultra Fi Dac, which sounds great when it runs, problem is what with apple updates, software issues, connectivity glitches, the system is a pain to use. 

Suggestions on what would be easier to use, potentially sound better and wouldn't cost more than $2k to upgrade?

I am not familiar with ultra Fi but you could switch to a more reputed DAC

Chord, Benchmark, Bryston, NAD, Schiit or Holospring

there is s nothing badly wrong with the Mac mini and iTunes - like most computers you get crashes from time to time. Chrome browser was a problem for me on the MAc Mini but on a PC it will be something else....
