Congratulations ECUPirate - my tax package is on it's way to you, can you have it ready for Aug 18th ?
I'm a little upset as I just spent 20 mins or so typing a reply, then I attached an image but when I posted it I was told that it was too large and of course my whole post dissapeared, so here is a shorter version.
All images of block can be found here :-

But please be patient as they keep closing it due to excessive d/l as I previously posted this on OC.com where I spend most of my time (same handle). Any questions, ask away.
I don't have my radiator yet, still hunting - if anyone knows where I can find a cheap Serck aviation H/E I'd be very grateful. What rad can I shoehorn into my Antec 1200 ??? Temps will probably be meaningless unless I can get at the cpu with a thermocouple (which I don't have), I have a Soyo Daragon P4S and I wouldn't trust the temp monitoring on that any further than I could piss upwind in a hurricane. I do have something coming though that may be of interest to you so hang on a while until I get it up and running and then I'll post a few revealing pictures (now, now, minds out of the gutter please).
The combined CSA of the channels is a little more than the CSA of the 1/2" tube that will be suppliying it, although the barbs are 7/16" ID (my next ones will be true 1/2" ID). The block should operate in the high velocity/turbulent domain but I want to reduce the flow to see the effects, the roughness was to disrupt the boundary layer if the flow was reduced to the point where laminar flow started to establish itself. I was going to shotblast the block but the only machine available was a beast and very indiscriminate and would have required a sheet metal mask to protect the upper surface. The answer to how I achieved that finish is in the picture - it took about 15 minutes but i found it to be very controlable, and whats more, it's readily available to anyone. The finish on the upper surface is from the shotblaster and it has also seen some wire wheel action. (a dremel engraver - that's my first block, I used it to experiment on
)
