Best PC to use as a Server

Sure this one has been asked before but I couldn’t dig up anything recent and this stuff changes over time anyway.  I use a Mac Air but it apparently is out of HD.  It is 7 years old and has been stuttering badly lately, especially since I loaded Audirvana Plus and dbpoweramp.  
  I am interested in a Windows based PC, because I want to run a Windows based program called MusiCHI and I also would like to have an HDMI port, which Macs don’t offer afaik.  I won’t use it for much else, maybe for surfing, occasional downloads, etc.  I haven’t owned a Windows Computer for years but use them at work, where the Dell Laptops that we are given seem particularly crappy to me.
  My daughter had a Sony PC that I demoed in my system a few years ago that impressed me, but it seems that Sony has gotten out of that business.  Is there any particular brand that works well for music?
