One thing's for sure, that Apple case is very well designed. Quite pimp. I cannot see the pump, but then again, knowing how Apple works, they could've done something funky and integrated the pump into the radiator somehow. I thought of that lying in bed about a week ago: Taking a big-diameter fan, like a Papst 172mm type, and placing a waterpump in the deadspace behind the fan, with radiator wrapped around the pump in kind of a helicoidal tube with radial fins, and drive the fan and pump with a common motor with a little plastic gearbox for the fan blades. Maybe Apple actually engineered something like that.
Also, the flow circuit is totally in series. From one block to the next block back to the radiator. If that was heatpipe goo, it would be pretty warm, and not very effective passing over the second CPU. So maybe it is a watercooler? Interesting.
