Ooops, I was just looking at the first page on systemcooling's page, I guess it just shows a typical interior of a 6 series for reference. Ya, as far as the case you're interested in, not too sure if it'd the best route on putting any rad up front, there isn't much of an opening for intake, I'd probably put the BIM2 out back but mount it outside of the case cuz that suckers thick, if you put it on the inside, it'd be tough to tube the cpu from the rad outlet, but it looks like you're gonna have to lose that slot above your agp slot, who cares, like anything sits above your agp slot anyway. Oh, I never even put that BIM2 in, I just returned it, Directron allows returns on their rads so I have no idea how it would've performed, but I'm sure the BIX I got instead performed better that the BIM2 would've.
edit: forgot to mention if the rad is out back it might be helpful to have blowholes for the side panel to get fresh air to the rad.
