I'm really cheap, I stole one from work.! a bit big compared to most of the ones you will find (2.5" by 3" by 3\4"), It is also very simple design a TT patern. But the tunneling is 1\2 around, so it allows plenty of water to run through it. I had to drill and rig a way to mount it to my Slot 1 cpu though. I screwed up drilling the holes to big so I have to use zip ties to hole it on the cpu. I cannot find small enough screws at the hardware store to run through the holes on the cpu!
I could very easily stick 2 tecs on this baby. All I would need is a big enough cold plate which wouldnt be to hard to get my hands on. Tempting!
