First thing you gotta realize is that Corsair did NOT make it to compete with other liquid cooled setups. They built it to compete with high end air.
That said, I would rather go with something like a Prolimatech Megahalems or a TRUE120. However that is only because my current rig is water cooled so the H50 just looks cheap and cheasy to me. Also the $78 price tag of the H50 doesn't really appeal to me.
