Supposedly it's the best WC kit around. The only way to get better watercooling is to get parts from different companies (a swiftech CPU waterblock/pump, a Dangerden GPU block, car heatercore for the radiator, etc.) It's the one I'm looking to get myself. I don't need to hunt around for parts, and I don't need to put an outrageous ammount of work into it. I plan on getting either a Maze4 GPU cooler from Danger Den or a swiftech one, oh geez, what's the model again? oh I forget. But I'm getting the H2O Apex and a GPU cooler anyway.
