Do you think that 15 1/4 inches is enough deskspace for a new iMac and a keyboard? I know it will fit, but do you think the keyboard would be too close to iMac?
There is about a 4" space between the top of my keyboard and the front lip of the aluminum stand for the 27" iMac and mine takes up around 17" of desk space. 15 1/4 inches should work but you're going to be sitting pretty close to the screen.
