I would just like to add that the motherboard you are currently set on buying does not have onboard video, and I see that you aren't planning on buying a graphics card right away. Unless you have an extra pci-e card lying around somewhere then it isn't going to be very easy to use your new computer : (, obviously if you don't intend to use it right away than thats okay though.
Also if you want to save a little money and if you plan on upgrading your graphics card later anyway you might be interesting in buying an x1900gt. They have a very good price/performance ratio (with oblivion on ultra settings, my fps never dips below 25). Other than that though I'm liking the build : )
