Thoughts please?

Budget:
Preferably something under $2600.

Expectations:
I've decided a while back that it was time to finally go out and buy a computer that can handle more work. I have never bought a customized computer before, although I've looked into them for a bit. Any advice would be greatly appreciated, (to be honest I am a little nervous asking for help). Originally I set my budget at $2,300 but I decided to raise it to $2,600. What I have come up with below settles around $2,500.

Usage:
Gaming, general tasks, and web browsing.

Special Needs:
None that I can think of. The room I plan on putting the computer in gets a little dusty since it is a small room but it's nothing major.
