... I have done six restores in the last two weeks – all for this one computer – so I have only four left now.
It is useful to know that following a restore, the .mjr file sent to you (that registers a copy of MC) works for 14 days, on any of your (your home) computers. You could have burned a single restore for all your experiments by simply running the .mjr...
I have several computers at home, and I usually have to use a single restore for all of them whenever I change MC or Windows version...
I just built an audiophile audio server running on Server 2012 core edition.
An "audiophile audio server" is an oxymoron : a server, by definition, serves files to another machine, that buffers and plays the files (the "renderer").
It is the renderer that you want optimized for quality (low fan noise, quality DACs or receiver).
And using a core edition WS2012 hoping to have "more polished bits with less jitter" is simply snake oil, do yourself a favor and stay
very far from that
