Osshead this looks great!
I'm looking at building a set-up with the rampage III extreme, an i7 920 and the corsair 800D case - in fact pretty much the same if looks.
After much reading and looking at options I discounted the corsair H50 watercooled kit to got for the Noctua NH-D14.
I must explain that I am too a watercooling-newbie and have not a clue as to where to start, though the idea has always appealed to me.
My main reason for watercooling would be the quiet operation (which is also why I've been looking at the Noctua).
But then looking at your set-up, it does look pretty cool!
Could you or Tom get in touch or post the component you have used, and maybe give me a bit of advise as to what I should expect look for?
Cheers guys!
