I can tell you right now, with having a water cooled stacker 830, that you will not want those components in that orientation. It'll make your life a living haties trying to move components, adjust for kinks, and just a nightmare of hair pulling.
IMHO here is a good setup.
move your hdd's up top leaving 6 bays open. That will leave you enough room to have a dual radiator in the front with fans. that way with the saved space you'll also have room for the pumps to be infront of the radiator as well. If you use a small enough res you can actually put the res next to the pump as well in the same location, b/c once you remove that hdd bay from the bottom there is plenty of room to be had. Also I want to comment, that if you go bigger than a dual fan radiator, you'll need to mount it outside, there just isn't enough room to be had. Not even in the place where you have your proposed location.
I have my fans in a push configuration.Edited by NCspecV81 - 6/16/08 at 10:51am
