LR concludes this is a nice self-contained cooler, that is easy to install and performs relatively nicely.

Antec has been a maker of PC cases and power supplies for years. Now Antec has stepped into the world of CPU coolers, both air and water. Today we look at the first self-contained water cooling kit, the Kuhler H2O 620. Join us as we put the Kuhler H2O 620 through the paces on our Intel Core i7 test system and see how it performs.

Quote:
"All in one kits are becoming more and more popular as some users want the benefit of water but either don’t want to build a custom loop or have the fear they may assemble it wrong and it leaks all over their system. The self contained all in one kits like the Kuhler H2O 620 are simple to install, maintenance free, and cost much less than its custom counterpart. The Kuhler H2O 620 costs close to the same as most high-end CPU water blocks, but not much more than the middle of the road blocks..."
