I hate to be "that guy", but google is really your friend, and there is a watercooling forum here complete with beginner stickies and what you need to know before you bother the masters. If you ask for the best, and they give you the best, don't say "ya but I really want to cheap out on this.", you asked for the best, they offered. With watercooling, go big or go home. From what I've read, and I may be off, but just to start a water cooling loop is like 200 - 300 USD, and once you start, there are a lot of parts you can use again, so you buy quality because you don't want to buy it again because a part failed, especially when you're playing with water and electricity. I really wanted a custom loop, but for my budget, I was better off going on air, and my little brother bought me an AIO for my CPU. My temps are lower than on my old Hyper 212, but my overclock, is roughly where I'm stuck at. It's not a temp issue, it's that my chip can't handle much more. Here is where a lot of people sent me for Water cooling. http://www.xs-pc.com/. Decent stuff, won't kill you on price. Start there and work up.
