Weird question for you guys. My G5 iMac bit the dust, so I am looking at purchasing a new iMac. I am struggling with whether to go with the 20" or the 24". Part of my problem is whether the 24" will be to big to fit on my desk. Can somebody with a 20" and another person with a 24" please measure the body of the their iMac and tell me how wide it is and how tall it is and then also how far off the top of the desk the body sits on the stand? Does that make sense? If I can find these measurements, then I can get a better idea if the 20" or 24" will be the best fit on my desk. Thanks in advance for your help.
