I want it big enoigh to fit a 24-27 inch monitor, keyboard on top(I dont like the keyboard underneath on the tray) Mouse and mouse-pad, speakers, and maybe a laptop or a few other things. Room for 2 monitors would be nice but not necessary. Also, maybe it should have a place to put the tower up off the floor. Not sure, but have heard that its bad to let it sit on the floor(my room has carpet).
