I walked away from using a computer for my audio recordings- linked to my stereo- long ago. I found that music streamers were designed, engineered and built for hifi or stereo integration and they serve the purpose much better.
Having said that, I don't have ANYTHING negative to say if my fellow audiophiles like using a computer and it works well for them. Great! I think a Mac mini is a great solution as well as many other computers that have a solution for reducing noise and that includes PS noise and interference.
