^^ what those guys said. Still, there are excellent air solutions available out there for ~ $50. If financially feasible by all means, go for water, but if you're going water, make sure its damn good. Otherwise, a good case with a decent air cooler will suit you just fine. Just to give you an idea, on air cooling using an Arctic Freezer 7, im getting temps of 53-55 celcius under FULL LOAD @ 3.4ghz!! So yeah, water is nice, but air gets you there as well.
