First of all; processor should be an i5-4670k now that Haswell has been released. The motherboard should be an 1150 Socket with the Z87 chipset (like the new Asrock Extreme4/6, or the Gigabyte UD3H). The RAM is alright, but unless you're planning on running X79 chipset (which you aren't) then you should definitely get 2x8 GB and not 4x4 GB. For the graphics card, I would try to find an on-sale Radeon 7950; you'll get much better performance, and it comes with four free games, I think. Your hard drive is made specifically for NAS storage (network-attached storage) so essentially for a server. I would recommend just a regular 2 TB, 7200 RPM, 64 MB cache HDD. Also, I would go for a case that has better cable management, as well as is smaller and cheaper; unless you're planning on running SLI (dual or triple) in the near future, that case is excessively large.
Mostly, the parts just need modification to current generations and specifications, especially the motherboard and processor.
