I've gone with a basic Swiftech 120 kit before and found that the pumps get noisy after a few years. Add to that the maintenance (topping off coolant) and my kit-based approach to cooling just the CPU was silly. Self-contained units like this is the way to go if you do a basic water setup. I'd love to get one and live a much simpler water-cooling life on this 2500K rig.
I'm in for one of these Kuhl CPU KUHLERs. Never had a problem Antec products. They have always taken care of me problems or not. Never had a CPU cooler from Antec so why not. Besides I got 3 cats and a dog.
It looks like a really nice alternative to full blown liquid cooling, without the hassle of actually getting it running properly, just need to figure out where you want it placed on the case.
