Drop the Thermaltake from the build - if you are going to go water cooled, at least get a decent unit. The unit you link recycles the warm air back into the case, which is so not where you want it...
But don't do water cooled - on today's processors, it's a waste of money, except possibly in the worst of environments (and some could probably argue effectively that it's not worthwhile even then). I have a watercooled system solely because I could reuse most of the watercooling from the previous AMD build (where it made a huge difference) and the motherboard was water ready, so I couldn't resist. But if I had to buy it all now, no way. It's probably the least effective place to budget your money.
