Have a look at the following sites, they should help:
http://www.dangerden.com
They should all do watercooling stuff, maybe kits - look out for ones with peltiers, you probably won't want one of them yet unless you can handle the condensation

Try www.millisec.com for Leufken’s products with better service at a discount. I’ll second the Dangerden recommendation. I’m currently waiting for Dangerden’s water block and Cooling Cube to combine with a Leufken pump/reservoir from Millisec. Both companies are great to deal with.
