Hi
Matiz, friend from polish purepc.pl forum, some weeks ago ask me about one really simple and cheap tube for cooling single GPU, like eg. 7900GTX :) . I had thought a bit, and that's specs : 42 mm pipe, 25 cm long, base 60x60x10 mm, 10 holes 8mm drilled in base :D = very simple, cheap and fast to make container :) + stainless backplate + 19 mm armaflex thick insulation .

I can also make that containers in SLI/CF kit :D
Holes for G80 won't be problem :) .
