How would you get around this with the Zalman? (from systemcooling.com):
"The only down side to this cooler is the spotty compatibility with AMD systems. Most of the problem comes from the fact that the processor socket often sits very high on the motherboard in AMD systems, which means that the cooler can interfere with the power supply in some case/motherboard combination. Given the large 109mm diameter of the unit, this sort of problem is practically unavoidable."
