I got the base made. Version 1 anyway.

My capature card is not being detected by Winblows XP Pro so my cam is still down. Will hook it up tp another comp when I complete this thing as I have a bunch of other stuff I need to take pics of to.
Anyway the base it 1/8" thick. Where the core of the CPU is it has pits I drilled into the block that are 1/16" wide at the top and taper down into nothing. Similar in #Rotor's design exept I only used 1/2"x1/2" of the area in the center of the base! I am going to have an inlet directly ontop of the pits. I have a few idea about the nozzel;
1) Not use one at all.
2) Do I high volocity one similar top Cathars.
3) Do a shower head type like Dodge Vipers.
Being I will use acrylic for the peice with the nozzel making new ones will be extreamly simple with the lazer at work. Couple slight adjustments with Correl Draw 9 and hit print.

It will literaly take about 2 minutes to make the center peice with the nozzel and all the holes. I am still not sure if 1/8" will be thick enough for the base yet though. I will find out when I get all the peices to put together.
The top peice will also be acrylic. That will cut time and costs waaay down. I do not see any reason to use metal if the center will be acrylic. Stength shouldn't be much of an issue either so I am not worried about it breaking. I may very well have to 1/4" for the base though. That would add some milling time.
My goal for this block is not high performance, but a easy to make yet decent performance block for entry level or quite cooling applications at a low price with a copper base
I do not see to many decent performance low cost blocks. Might find myself in a decent market.
