I'd been hanging on for the 2011 Mac mini refresh, and when it was launched I dashed out to pick up the fastest Server available (assuming that was the fastest mini available). A few months later I was surprised to notice that whereas my i7 server runs at 2.0GHz, there's a BTO option for a i7 that runs at 2.7GHz for the non-Server model (only). I would have definitely gone for that option with the Server had it been available, but it's not available for the Server, even BTO. My i7 Server certainly runs warmer than my older mini. Do we assume that the extra drive in the Server model does not allow enough cooling for a 2.7GHz i7 option, so it's limited to the non-Server model with a single drive? Could there be another reason Apple doesn't offer a Server with i7 running at 2.7 GHZ?
