I'm buying a new 27" iMac tomorrow. I'm going with the 2.93ghz i7 processor upgrade and leaving everything else the way it comes. I'm sending it to OWC to have them put in their 60gb ssd, 2tb western digital caviar black hdd with 64mb cache, and 8gb ram. All in all its going to cost a little over 3k. Good build? I'm open to suggestions. Thanks in advance.
