Here is the concept:

The left most diagram is the top of the block. This will fit a 1/2" barb.

The right most diagram is the middle of the barb and also the jet impingement nozzle. This piece is seperate so that it can be modified to fit the mounting holes on your board and the nozzle can be drilled to taste.

The center diagram is the base of the block with two 3/8" barbs coming out the sides.

On the very bottom will be a copper plate of user-defined thickness.

There will be three O rings used in the construction of this block to ensure no leakage. The top portions can be made out of any material you desire, though I personally would use a clear plastic for ease of construction. When stacked and the four screw holes are aligned, screws will be threaded from the bottom to the top, and will be bolted down tightly with nuts (not of the deez variety) on the top.

The system pressure will ensure a lack of hot spots inside the block. How?

There will be positive pressure at the top inlet and negative pressure at the two outlets due to the pump. Due to the offset outlets, it will cause a swirling pattern to appear in the coolant as it leaves, pushing the old hot water out and leaving only nice and fresh cold water. This also will use the jet impingement to focus on the "eye" of the swirl: the place right over the die itself.

I have been thinking on this for months, ever since an old waterblock design thread. What are your thoughts? If made out of lexan or acrylic, it would be quite a looker, and I personally think that it would perform extremely well while (depending on the size of your jethole) limiting flow loss. It might not be on par with the White Water or such, but I think it may be a very simple block for a newbie to make on a weak drill press ... and one that will perform nicely as well as be a centerpiece for a window mod.
