Just got my 27" I7 today after a mere 2 1/2 days of waiting(B&H), and everthing on it is great. No flickering(updated as soon as I started it) and there is no yellow tint. I only have one concern regarding the running tempuratures on these computers. I'm used to my older liquid-cooled G5 Pro that always ran somewhat cool most of the time. But after using my new iMac for several hours, I put my hands behind the screen and noticed that it was really hot. Is that normal on these? Maybe I'm just a little paranoid, but I'm not used to computers feeling so hot on the outside like that. I took a quick screenshot of the temps incase anyone was curious. Help?
