Water cooling has it's ups and downs. It is a little bit more complicated to set up than regular cooling, but definitely has better cooling flow, and it's quieter. It's a great idea for small cases when you still need lots of power. If you have a bigger form factor (ATX, etc) regular cooling is cheaper, easier to set up, and just as effective. The only noticeable difference is it will be louder than water cooling. Best bet is to get an idea what it would cost for either, and make an informed decision.
