Well we all know about the ebuyer zalman HSF clones, but how about ThermalTake new watercooling 'Rocket' that looks very similar to the reserator.

It seems to have the same pump as previous models of their cooling systems (i think).
The page shows a diagram of how the water traverses through the rocket - is this the same way it is done in the reserator?
