I will never return to air for the majority of components on my personal builds.

Water has so much more thermal mass and is so much better at moving heat. That being said, if you don't build it right from the start you will have nothing but issues with it. Prepare to spend the money for good components, the time to assemble it, and the time to test for leaks, and the time to keep it running smoothly.

I vacuum out my radiator every week, and every few weeks shut down and blow it out backwards with compressed air, then check the coolant level, and fittings for leaks with white kleenex to make sure i have no leaks.
