ok, maybe I missed something, but have you thought about fans? I mean, I know he could go Yate Loons, but if he wants something a bit better...you know...just a concern to mention. I think you're going about this too fast. Have you read the sticky from this section (read every single link)? Have you read up on watercooling basics and what you do once stuff shows up at your door? Do you know if your case is capable of watercooling? there's a lot you have to learn, it can be a blast, but don't rush into this, you're posting, so obviously you have a working computer, so why rush? Take your time, read the stickies, hit skinneelabs.com and read some (read ALL) reviews, go over to xtremesystems and read their stickies. Keep in mind while doing this that watercooling has evolved, so don't make it half way through, feel like you have seen it before, and stop, read it all, even if its just to pound it into your brain. We love helpin people here (least I do...), but what fun is it if we do it all for you?
