So now it would be CPU to NB to GPU inline. Also took out the GF4 MX and the mounting holes are totally different from anything I have seen so far.

Very glad to hear you are setting up your test bench Jaydee. Good for you.
I have few more question for you on my ideas. How large should the pin fin area be for full a proper cooling of a ATI 9700-9800 die?
I'm going to recut/shape a Akasa one piece copper 1U pin fin sink to try to make a block along the ideas discussed here. While the pins are smaller (1/16"), round and more densly placed, I hope to be able to make a block with a top along the lines Tex707 last showed. This air sinks base is 3/16" thick with pins being 3/8" tall. So I need to both remove many of them and shorten them by about 1/2 the height they are now.
As this base is thicker than has been shown to be ideal for cooling I could cut some grooves between the pins with a reinforced dremel cutting wheel, it's just the right size to fit through between the rows of pins. But would the roughness and narrow width of these grooves be self defeating (stagnant flow in them)?
Last I don't have anything beyond a dremel at the moment to try to cut the O-ring groove. Thinking I'll have to use some Marine goop instead.
Tex707,
You're right of course about the angle being at it's limits. Your cut away of the design made that plain. I wish I had thicker Lexan to work with, but the thickest I have is .5" at this time, and not much chance to get any that's thicker for a bit.
While I found the stress work interesting, you used acrylic, but Lexan (polycarbonate) is FAR stronger (approx 30X I think) for a given thickness of material than acrylic. Would not Lexan pretty well remove stress risks for the design?
Thanks to all for your continued help and advice.
