Hear the H50 can't compare to the high end air (temp/dollar or temp), why'd you go this route?
It seems to depend a little on who you ask with regards to it competing with high end air cooling.
However, the main reason I opted for the H50 was noise levels. It is basically silent; the only noise comes from whatever 120mm fan you are using. Heatsink/Fans I've used in the past have typically produced a lot more noise. Also I like the look it gives, but that is personal preference.
