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?

I asked this myself in late 2016 https://forum.audiogon.com/discussions/looking-for-laptop-windows-10-for-music-only Folks recommended Eluktronics as a laptop and they seemed like a good choice as the mfg says they are loaded with basic Windows and no bloatware.  Looks like they have a good discount on now. 
I ended up just running my old Samsung series 9, upgraded to Windows 10 & Jriver 24 as my program.  It works really well.  If you've never used Jriver the learning curve is huge.  (For me anyway.)
Good luck, John

Take a look at the audio specific pc's, headless, controlled from your phone, iPad, or laptop. 

I have, over time, used three of Small Green Computer's models. 

There are other pre-built and supported options or you can build your own.

Thanks, I had never heard of eluktroniks.  The offerings look interesting and yes it does look like there are some sales going on.
look at small green computer, the inexpensive i5 linked should do what you need but they also have a more powerful i7 variant in a couple of configurations.  Using these for Roon core and then using the ultraRendu, Metrum's Ambre, or something similar as the endpoint should be a very satisfying sonic solution.

for mac type solutions, you might also look at Mojo Audio
