I'd just bought the first gen. intel iMac 17" 1.8Ghz CoreDuo, love the design. But after a few days of use, the iMac start to sudden turn off by itself, and refused to start up for a long time. Luckly, I was able to return the iMac to the seller and get my refund... But, I really love to have a white iMac, so I'm now still keep searching, my ideal will be a 20" core2duo intel iMac (white). However, after read all the post here that I seen many people got problem with their white iMac, some have the shut down/unable start issue, some have the screen defect problem... My question is, which build / model of the intel iMac should I get for the next purchase, I just hope I wouldn't pick another defected one and need spend extra on repair... Thanks in advance.
