Hi all
I´m planning to make my first waterblocks. One for the CPU and one for my Gf4.
After looking around in this forum and trying to soak up any ideas and pro/cons I think I made twa quite good designs.
For the CPU I´m aiming for a jet block. The reason that the channels looks like they are is that the tools needed are available here at work, and the material is free

. Copper 8mm bottom with acrylic top.
Because of some space regulations I tried to make the Gf4 block as small as possible. 4mm copper bottom with a soldered brass top (slightly transparent on the pics....).
Sooooo what ya´ll think? Is it a good design, what can I improve?
The first two is for the graphiccard and the others are for the CPU
