Hi A few questions about quad core mac minis: I noticed on the Wikipedia (http://en.wikipedia.org/wiki/Mac_Mini) that the 2011 quad core Mac Mini Server has an enormous greenhouse gas output relative to regular models (around 1,130kg vs 280kg). Anyone have any idea why? Also, is it possible to "downgrade" to regular OS and would there be any power consumption benefits? Finally, is there much difference in performance between the 2011 mac mini quad core server and 2012 quad core (non-server)? Thanks in advance!
