AQUAEXTREME 12 volts PUMP

i have the chance of buying this pump from someone i know.

AQUAEXTREME 12 volts PUMP with 1/2" inlet/outlet (equivalent of swiftech MPC600) is it really the equivalent of the 600? or should i just get the d4/650?

also i can get the mcw50 gpu block from him at the same time. how is the mcw50 compared to the fusion gpu block?

it's the same as the 600

as for getting the d4/650, compare prices and decide for yourself
