How does this look?
Thats a top down view (to scale) of my 5.25" bays.

The black block on the far right is the radiator, mounted right at the front of the 5.25" bays, then next on the left is a 1" shroud, then a 120mm fan (also 1" depth), then another 1" shroud on the opposite side, so the reservoirs (adapted version of Trodas' Tank o Matic) don't get to close. The big red block in the background is a Pioneer DVDRW drive which'll be right at the bottom of the 5.25" bays.
