That cooler not even is 1 mm higher than the Hyper 212 Evo which has room to spare in the Antec 300 case. The fan can be raised a bit if need be (as long as the case provides enough clearance). As can be seen at http://www.legitreviews.com/cooler-master-hyper-612-version-2-cpu-cooler-review_161375/3 the fan clears the memory slots; your motherboard has even more space between the CPU socket and the memory slots. There are no obstructions or limitations.
