that is one great design nubius. shame i cant do the same, as the mobo in my dell is on the WRONG side of the case, causing the gfx card to be the RIGHT way up. this means as it is pci-e, it is at the top, so i have not slots above to put a homemade cooler in. oh well. its a great idea though.
what happens if you try the 6800 at night, with all windows open?
