Where were you thinking you would put it? The bottom is the only place I could see it going. After seeing the front of your case, maybe a single loop with this rad might be a better idea:

or

With the Feser you would probably need to do a slim DVD drive, but I think either would be enough and save on space. You could also move the Hard Drives back and do a push pull configuration or fan/shroud combo. Basically you would just be adding the GTX285's to your current loop, so no need for additional pump and res for a second loop.

Just a few thoughts.
