Like Brian said, it'* best to build your own. Start with a powerful/reliable pump, find or make a good radiator, then find liquid blocks for all the components you want to cool. I need to get a block for my mosfet as well. I went the cheap route and got my bigwater, which is nice but doesn't cool enough for what I need and its only got my cpu on the loop, I need something BIG to run that with the graphics cards and the mosfet. I'm sure you know how much heat those cards put out, and I've got the Super Super clocked edition.
