I've read a lot of threads about people saying that their iMacs are hot to the touch. Mine is just the opposite, mine is barely warm at the top and almost cold on the bottom (backside). I've had it up and running all day today and istat show the cpu temp of 95*F/37*C. NICE. 
after reading all the bad threads about people having problems I was really worried about buying a new iMac, but I have had zero issues (screen, hd, temp)
