get 2 MCr320s in that price range
I am not normally a Black Ice fan... but have had some pretty impressive results with the one I got from CP.

$130 new.. used I am sure you can find it for half that.. Addon some 38MM fans and you should be good to go.
Fro 120.3 thermochill or the fessers I believe are best performance. (not sure on Fesser prices I know I have seen thermochills on other forums at $100 or less though)
