To be clear, these Mac Minis are running regular OS X, not OS X Server. I bought one of these back when they first started, using PPC Mac Minis, and everything was as advertised. My motivation at the time was basically just to see if there were any major advantages to using OS X on the server, over Linux (I was using and still use CentOS and Debian on other servers). I didn't really find any such advantages, so after the contract was finished, I had them send me the Mac Mini.
