Today, my iMac finally arrived from Ireland: Awesome machine! But I'm quite unhappy with the build quality. The first quality issue is pretty obvious: A notch in the back of the aluminum body. My second complaint is about the gap between glass and aluminium chassis on the left side. Is this ordinary for 27" models? I do have a 21.5" 2014 iMac for comparison, which has no gaps at all. Do you have this kind of gap between display and aluminum chassis?
