I have heard that the midplane of the new iMac had to be completely redesigned to encorporate the new video card. Anyone willing to open theirs up and take a picture? I'm not patient enough to wait until mine gets here next week. On a related note, hardmac.com reports that Apple has scrapped the DIY repairs for the new iMacs, except for the fans. Maybe this is why Apple hasn't updated any of the DIY documents on their website.
