Hey folks, my wife and I want to upgrade our 2011 iMac to a possible sad and do not want to risk doing it ourselves. We were quoted about 129 to have it done at our Houston area microcenter and was wondering if anyone else have had this done before by them? We also have a MBP and a retina MBP and about 900gb between us on these laptops. We would like to make the iMac the main storage hub for our photos and media as well as be able to run windows 8 for 3ds max so maybe a multiple hard drive iMac would be more feasible? Any experience or recommendations?
