He's got some router that is computer controled and can do really detailed work as well as cutting chanels (4 waterblocks!)
So I got to thinkin.

I wanna make the following:

HD water block:
2 sheets of copper that have identical chanels and a grove 4 an o-ring screw 2gether, add barbs
presto, a HD block.

Northbridge:
base of copper, cut chanel (should I use a mini spir@l or more like the maze1?) add acrylic top & o-ring.

GPU
I'll design a block for a GeForce4 TI and possibly ram sinks.
again, prob will be acrylic topped.


so here are a few Qs

1. where can I get copper (I want it to all be copper to prevent corosion, so no Alu!)?
2. how would I cut copper? (is this something that normally can be done at the shop?)
3. would there be an issue with the acrylic tops? DD and the other north bridge and GPU blocks I've seen are not acrylic topped, is there a specific reason 4 that?
4. where would I get o-rings?

any general advice about these sort of things?

when I gear from the guy's dad, I'll plst prices to see if they seem fair.

Thanks for any help. I'm 100% new to metal working.
