Hey, I was thinking of perhaps hooking up a 20" Apple Cinema Display to my 20" iMac so I would have dual screens. But I was just wondering if the iMac and the Display itself (ACD) were the same height so that the screens and aligned. I checked Apples website and found the height in inches but i'm still not quite sure. I just don't want one screen to be at a different height than the other one. So if any of you out there have done this, please let me know what you think or if you could post a picture that would be even better. Thanks.
