between the upper and lower chamber where the black sliding cover is
I slid the black cover all the way back and enlarged the hole to match
almost lines up perfectly with the fan intake on the second 8800 . all the power wires
I re routed along the right side ( trimmed partition in lower chamber) to a new hole cut
at the corner of the drive cage . swapped the fan from the lower partition to the rear vent . fan from the rear vent to lower chamber. fan from top case hole to
front of case intake. closed off top case hole. lower card although it only has a 1/2 inch or so actually idles @ 49 degrees top card idles @ 53 degrees
