I just got a Swifttech H2O 220 Kit off the Egg for around 130$. I love it. It's got some great reviews as well. I think you will find that the Bigwater 760 will perform as well as a High end air cooler. Read some reviews and check some sites.
If you want a good kit I would suggest something like this which is a good kit with good expandability at a very good price. The H2O 220 has gotten very good reviews but with my suggestion you have a conventional water cooling setup that you can expand or change as your needs change. Or for $380 you can get an all in one system like this that includes everything you'll need.
