CPU: Changed to Xeon 1230 V3, I always recommend this CPU for professional users that do not overclock. This CPU is rated very similar to i7-4770K, but just without integrated GPU and not good for overclock. However, both factors do not concern you.
Motherboard: Changed to Gigabyte GA-H87-D3H, really nice H87 motherboard that is compatible with the 1230 V3.
RAM: Changed to Ripjaws X Series 16 GB, same thing, but cheaper.
HDD: Changed to Seagate Barracuda, WD Black is not recommended by me especially to system where SSD is implemented. The premium for WD Black isn't worth the performance. It is a decision between WD Blue and Seagate Barracuda. Barracuda is cheaper in this case.
PSU: Upgraded to Antec HCG-620M, very high quality and cheap.
OS: Windows 8.1 64 bits for 16 GB of RAM.
I highly recommend this build, ask me if there's a question or concern.
