Actually, I've not gone with liquid cooling... yet... I'm still experimenting with air cooling my processor to see how well that will do. Not to say that I won't go the liquid route at some point in the future, I'm just not there yet. Besides, WHEN I do it, I will do it right, and probably not on the cheap. I want to make damned sure that I won't have issues with the setup, so I'll probably pick up a cheap PSU to test out the entire configuration before installing it. If I go 100% internal, I should be able to assemble it outside the case, test it overnight (or two) and then just install it into the case.
