Swiftech makes some nice stuff. They don't sell kits. Stores purchase the aprts and group them together. Swiftech makes top CPU and GPU blocks and some very good radiators. They buy Laing pumps and rebadge them under their name.
Start at the top of this forum, read for a week, read hard, take notes then ask again.
THIS is a nice starter kit.http://www.jab-tech.com/Swiftech-H20-22-Ultima-XT-Liquid-Cooling-Kit-pr-4324.html
If you can't do it on your own with some hard work, spending a few weeks on this and other forums reading lots and lots of posts you can ask at Best Buy. They have salespeople payed to help. Too bad there is no watercooling there.
Your kinda on your own, it's ALL up to you.
Tough love, but thats the way it is......
