Why do you need another drive ? the bluray one, i'd ditch it if you're not planning to add any bluray discs.
You don't need 16GB of ram, get 2x4GB, 8GB is plenty.
Get a ssd with mlc nand, like the kingston hyper x, crucial m4, samsung 840 pro, sandisk extreme, etc.
If you're planning to overclock the cpu, get an aftermarket cooler like the xigmatek gaia or cm hyper 212 evo.
If you can upgrade your card for the 7870 XT, it will be better, the 7870 XT is basically a 7950 under the hood.
You can find one at 240$.
