True, but you really don't need a loud CPU cooler since you have such a large volume of cool air blowing down.
I mounted a extended ATX board in mine, supermicro H8DCE, and had to drill three extra holes in the tray. I didn't tap them, I just added nuts on the back of the standoffs.
My bigest complaint is the audio cable could not reach the AC97 connector which is a few inches from the back on the left.
