Being big fan of Mac Minis I was looking to replace my main MM 2009 2.6Ghz for something more current. Well after 2014 release I have doubts about 2014 MM values anymore therefore I decided to snatch 2012 i7 2.6ghz for $839 before they are gone forever... However I still can get i7 2.3ghz version for much less, $230 be exact. My main question I need to help - is 2.6Ghz BTO version really worth of extra $230? I'm not sure if heat/noise between those two can be any deciding factor besides the price. My another MM 2011 i5 feeding 55" TV screen flawlessly is used for HT only. Loaded with 16Gb & 500Gb SSD is most likely overkill for streaming so I'm going to swap memory with either 2012 model for sure. Obviously 2014 is not cost effective for me since for similar 2014 MM i7 16gb SSD I would have to pay much more. TIA for any help.
