The Graphics Card is A bit too long, you will have to take out the drive cages to fit it in. If you are just gaming, I recommend this:

I might change what I said earlier, the 780 is a strong graphics card and will be for quite sometime, in the future you can SLI the card, I have changed the case to the Fractal Design Define R4 if you don't mind, I have this case myself and it is great, I can practically not hear it when it is on, it's easy to build in, has nice looks and a clean aesthetic. There are many strong points about this case, I have changed the Cpu and CPU cooler, The CPU is the i5-4670k, I chose the 4670k over the 4690k since it's about $30 cheaper, Also I have chosen i5 over i7 since the i7 is overkill for gaming and won't be noticed unless you are using heavy tasks like rendering. I also have the 4670k and is a great CPU The CPU cooler is also one I have, The Hyper 212 Evo will overclock great with a tremendous price tag, I managed to get 4.4ghz once on my cpu, The Cooler is like the Moto G of CPU Coolers,
If you want to spend just a little more than the amount that your build was, Here is a build that has a GTX 780ti in it:
