Hardwarecanucks posted a review of the Magicool Copper CPU Waterblock

Air cooling thy name is mud. At this kind of price, there's no excuse not to take the plunge and go for water cooling. The cost of the Tuniq Tower is $55, and for only $37, this little block kicks the stuffing out of it.  The thing to get over is the initial investment. The reality of it is that it does cost about $150-$200 to put together a decent watercooling setup for the first time, but many of these parts can be reused and upgraded later.
