* Swapped out the GTX 670 you posted to the Gigabyte Windforce. Mainly due to the fact that it has 3 fans. Better cooling = better overclock
* Changed the i5 2550k to a i5 3570k because the new batch of SandyBridges overclock poorly and the i5 3570k will take advantage of the Z77 motherboard.
* Switched a new motherboard in, as listed above by stulid.
* Added the case you chose. Looks a fantastic case.
* Power supply put in. Modular and will allow to SLi in the future.
* Upgraded the SSD to a better and higher capacity one.
* Changed the HDD to a cheaper one (but still performs the same).
* Put in a cheaper Blu-Ray drive.
* Swapped out the RAM for a cheaper kit. Still great, and the difference between 1866MHz and 1600MHz is minimal, unless benchmarking.
