Personally I would stay away from water cooling kits IMO they aren't worth it. If you want to water cool take the plunge and just do a custom water cooling loop. With a custom loop you can design it yourself with a little know how and planning. You can also get water blocks for not only the cpu but you graphics card, chipset etc thus you can extend it. With the right design they will way outperform closed loop water coolers. Closed loop systems are restricted to just cooling the cpu and pre-built there no room for customizing them. Also I'm not crazy about the pumps they come with. I can't tell you how many I've seen with pump failures only after a very short time. The last thing is the who rad system and cooling isn't enough it's performance really isn't much better than high end air cooling.
