I am a new member of the forums. I am researching the iMacs because I want to buy an Apple come April. I visited the Cleveland Apple store yesterday where they had 5 iMacs on display. Each one I used (played the games, used Photoshop, etc.) ran perfectly and beautifully. I have heard many stories about people buying iMac G5's which had problems like fan noises, display problems and alike. I searched for a similar topic but I couldn't find anything like what I am asking. If you own an iMac G5 please reply. In your reply please post your model (1.6 GHz 17", 1.8 GHz 17" or 1.8 GHz 20") and if you had any problems with it and if the problems are ongoing or have been corrected. I am wondering if maybe the noise and heat problems are a result of a smaller 17" body whereas the 20" has more room for heat to escape. Thank you so much!
