I think I should do up a new version of my old article where I build and ultra-cheap watercooling setup. The UnaBlock doesn't appear to be available anymore. But I found a nice cheap replacement.. Like 99cents cheap.. Tho you'd have to add your own hose barbs and come up with a hold-down for it.. And I'm not sure it's wide enough for the heat spreader on modern CPU's.. But anyways, have a look..

Far better quality than the UnaBlock was.. Still aluminum like it was, which I remember was a huge sore point with a lot of people. I think modern coolants have kind of put that problem to bed, but kinda defeats the point of running a 99cent waterblock if you have to spend $40 on the coolant it requires.
