I personally don't have experience with the TT Aquarius. I was originally planning to purchase that kit, but I decided to purchase the Corsair HydroCool200 because of the excellent reviews I read about it, decent price for a kit that includes everything except water, an external unit so less things inside the computer, turns on and off with the computer, and didn't need to cut anything for electricity. Here's my
review of the Corsair unit. I'm about 99% sure that Monarch still has the best price on it, if you decide to purchase it. Last time I checked Newegg had it for ~$230
