I took delivery of my 27 i5 3 days ago and so far everything has been "perfect" zero screen issues that I can tell, no sound problems, etc.
It is also a 2010 model, damn thing is practically brand brand new.

Sincerely hope that everyone elses iMacs ship perfectly or are replaced with ones that work properly. I'm not sure if I could deal with replacing it 4-5 times in a row like some. GL fellas.
That's interesting that some people are getting USA built Macs. I live in the U.S., I would prefer a USA built iMac rather than China. I don't like that it ships all the way from China to the U.S.
