I purchased a Mac Mini in the fall of 2015 with the intention of building a dedicated music server. In the process of researching my options, I found there were a few folks out there that will modify the Mini with an external power supply. I read some good things about Ben Zwickel and Mo-Jo Audio, so after numerous email and phone conversations I sent my Mini to Ben for the upgrade. It took only about a week and I couldn't be happier with it. I have begun the arduous task of re-ripping my CD collection to AIFF, so I feel you pain. I use dbpoweramp to rip with and have been very pleased with it. I also purchased Mo-Jo's asynchronous DAC, Mystique 2.0 and have been very pleased with that, as well. Lastly, I store the files on a Synology NAS and use JRiver Media Center as the front end for the whole thing and it all sounds terrific.
Good luck and enjoy the music.
