27", i7, SSD + 2TB HDD no apparent pixel issues doesn't seem yellow very faint whine from one click below max down to about 5 clicks above minimum. I have to put my head next to the computer at a certain angle to hear it. I think that if I hadn't known to look for it, I wouldn't have even noticed. Hitachi 2TB HDD, no noise to speak of I have a box with 16 GB of Samsung RAM from OWC ready to be installed. I suppose I should run the factory configuration for a while just to make sure everything works, but it's hard to wait. I was a little nervous waiting for the computer to arrive, given the various issues reported here. But so far...seems awesome! Exactly one week from order to delivery. Assembled in USA: That was a nice surprise; I didn't know they made them here.
