I'm working on putting together design ideas for a rackmount system with centralized water cooling. I'm planning on using all copper blocks, and PVC piping and silicone tubing wherever possible. I am finding, though, that PVC valves are an expensive PITA to get and work with, though the brass ones aren't. Similarly, I've found some absolutely outstanding stainless steel rads online for next to nothing that I could use in an array configuration. Will the brass and copper interfere with each other? Will the stainless? I'm actually looking like I'm going to be putting all this together in december (though only one machine in the array will be on the cooling loop at that point ... the other goes on in January with a new mobo/cpu ... I don't want to WC a slot A athlon), and I'm trying to get all the information together I need. My thought is that I'm going to isolate each rackmount component with a butterfly valve and have the butterfly valve equipped with quick-disconnects (like for hydraulics or pneumatics) to make maintaining the various systems easy. The only problem is I don't want to worry about corrosion. Any input?
