I would beware of water cooling if I were you.
I have a buddy who's a systems analyst & programmer with 15 years + experience (which I mention only because he's a guy that makes a good living in the IT/IS industry who's generally respected in his field, not my pal Timmy who's building his first box) and he's had 2 leaks in the last 6 months.
He bought the water cooled case Tom liked best, I don't remember the brand.
Anyway, good luck if you do, I never want to take my whole box apart to dry out parts and then try to see which ones still work.
BTW- the company is hosing him too.
