GPU block design

Quickly playing about on flash, I've designed a GPU block that should be easy to mill out. This is going on an X800XT, and I'll also knock up some ramsinks out of some 1/8th plate I've got knocking about. If anyone's got any thoughts / comments, let me know


:edit: the two white lines at the bottom denote the rough width of the inlet / outlet connectors, standard 1/2" barbs, drilled to 10mm ID. the rest is fairly self explanatory, water round the white bits, copper is the orange, and inlet / outlet I've yet to decide on exactly whether I'm going for straight or 90 degree mounted barbs, doesn't make any odds atm as I'm not SLI / Xfiring, but would be nice to have straight mounting or perhaps reverse mounted to come out the "right" way up when installed in a tower case...

Cool design,

What depth are those channels going to be?

About 7 - 10mm channel depth if I'm milling out of 1/2" bar stock. I've just had a bit of a brainwave though, involving the 1/8" plate. I might actually be better off going for a design that utilises lots more thinner channels; Maybe if I had a "U" shape, where the water flowing over the U channels went over the GPU on the curve of the U, taking in the ram as well, I might be able to have my cake and eat it as far as flow rates and restrictions are concerned. I've been playing around with a similar design for a peltier WB system for a while now. Simple flow direction through the thick poly top, lots of fine channels evenly spread, then back out again... I'll think some more.
