I see custom cpu blocks.. what abotu GPU?

I don't remember seeing any custom GPU blocks that cool the GPU and the video card ram. Did I miss something? or is it just something nobody has bothered to do yet.

I actually just built a custom one today. All though it's nothing it's still a prototype for a fancier one I plan to make. Im waiting to see if it works though till I get a radiator for it and find my pump.

I'm doing a semi-rough sketch for a 6800 GPU block right now myself. Semi-rough meaning I don't have my 6800gt yet and I'm going off pics and diagrams I see online and posted specs.

Now I'm sure the answer would be "yes" but would there be a benefit to cooling your GPU and video ram in seperate water flows? Seperate WC line?
