Maximum PC

I want to have my PC water-cooled this summer. I'm probably going to have to go with a custom set up because I want to cool at least my CPU and two video cards. I may also want to look into cooling my northbridge and 2 hard drives. Can anyone recommend a company that sells good water cooling stuff? I've heard Danger Den is good? Is this true?

Second, I may get a new case. I have the Thermaltake Xaser III right now. I may get the Thermaltake Kandalf when I change to water cooled. I've heard nothing but good things about the Kandalf. Can anyone recommend a better case to water cool with? I've always liked Thermaltake, but am always open to other companies as well. The only thing is that I'd like plenty of room to work.

Thanks.
