BladeRunner,
First of all, must say that I enjoy looking at your handy work and give applause where it is needed and well deserved.
I was wondering about those CU fins that you have in the pics.... would it be possible to make a RAM block that consisted of those fins in contact with the water and have maybe some sort of plexi-glass casing? Use screws to keep the pieces together and maybe some sort of "glue" to keep them sealed?
Probably would not be soo bad at cooling and MUCH lighter
If you would be willing to make something like that, I would pay for it

Got my own GeForce3 waiting for a great solution like that.
Again great work on the all CU block but I must agree that it would be a bit on the heavy side + CU waterblock for the core + water.........
But CU is the way to go for better performace and NO ANTIFREEZE!!!!! (dislike antifreeze
Thanks and good luck on future projects!
