They're absolutely right about the prices on watercooling kits. The first, and only one for that matter, I bought cost me just over 100 dollars. Was called iceberg.. needless to say it was a piece of junk. Basicly I got the same cooling from it that I would from a facorty HSF, but just no noise. It was not worth the money. If you're planning on getting one, be VERY sure it's a good one and ask others who have experience before you purchase it. Something I wish I would have done at the time. From what I have read in the past, some of the best watercooling systems there are come from
www.dangerden.com. I'd suggest you have a look there and if you have any real specific water cooling questions that the TFP posters can't answer,
http://www.amdforums.com/forumdisplay.php?forumid=35 is a great place to get it answered.
