XtremeComputing posted a review on the XSPC X2O Xtreme 1/2" CPU Universal Water block

I have to say one of the best Value/Performance CPU blocks on the market, if XSPC keep this up and release more excellent performing hardware like this they are sure to become as well know as the other major brands out there. A bargain and a performer all in one package, not something you see very often
