I'll talk you through a couple of things.
This build is predominantly focussed on a Graphics processing course, but will also annihilate just about any game out there at the moment at the same time.
2600k Annihilates anything that AMD has to offer at the moment in terms of well, everything....
Motherboard is just a standard motherboard, it does come with SLI support, if you wanted to SLI those 580's at some point in the future.
Sound Card and Headset are the ones you wanted so just went with them.
PSU, is a good brand, and 950W means it'll be more than powerful enough, should you choose to add another 580 in SLI at a later date.
The Solid State drive - to not include one on a build of this cost would be insanity. 64GB, should be big enough to install W7 on and your core graphics design programs so that they run nice and swiftly

Case - presumed that was personal preference.
RAM - Got you 8GB, will notice it in a graphics design build.
CPU cooler - you chose the H70, which wouldn't be my personal choice, but presume you chose it for the quietness element.
Picked the same Blu-Ray drive as you - simples
HDD - Why get 2x1TB when you can get 1 2TB for less... Unless you plan on RAIDing them then you might as well get 1 2TB.
Oh GPU - a 580 will eat just about anything you throw at it, so you're not losing out here, also I'm pretty sure I remember reading somewhere that some graphics programs are starting to make the most out of the CUDA/PhysX that you can get in the nVidia GPU's (Might be wrong here, can't quite remember)
