Sorry, another SSD thread. For a mid-2011 iMac which SSD do I need - SATA, mSATA, or some other? I've looked at the video detailing the install at OWC - http://eshop.macsales.com/installvideos/imac_mid27_2011_ssddiy/ Is there a better one? I've got some small screw drivers. Do I need to buy an install kit as well? Thanks for the feedback.
