Thats a very nice build. The only thing I might change on it would tbe the PSU. I know XFX makes good video cards but I dont know how good their power supplies are. If I was going to build a system like that I would at least throw in a nice Corsairs PSU. Other than that... not a huge fan of the case but it looks like it has good airflow. A case that I may submit for your consideration would be the CoolerMaster HAF 922. Its $99 and is very nice.
