I wouold say that all your choices are compatable and will work together however I have suggested a few changes. The cpu cooler can be upgraded to the new release from Zalman and the power supply can be upgraded to a better brand as I don't believe that Cooler Master is known for making good psu's were ANTEC is. I like Cooler Master cases but not thier power supplies.
