Your choice of Motherboard and PSU are excellent. ASROCK can make some damn good boards, and Seasonic pretty much make the best PSUs on the market. However, I would make a few alterations.
For one, your getting a Motherboard that's basically made to overclock CPU's, so I would recommend the FX-8320, as it's exactly the same as the 8350, just with a lower factory clock. So save $40, and overclock instead. They behave exactly the same.

Also, as The White Hunter said, if your not going to be using up all 8 threads on the 8320, you may want to consider the FX-6300. Since it uses quite a bit less power, and in turn creates less heat, you can usually overclock it higher than the 8320, which will give slightly better performance in games. It's also quite a bit cheaper. I'd say give it some thought, you can always resell it and upgrade to the 8320 if you ever need to.

The RAM you chose is a bit expensive, you could pick up this stuff here for a decent amount less. It'll act the same, and be just as reliable.

As others have said, I'd get a smaller SSD and supplement it with a traditional drive. Unless of course you already have some.
I'd also get a cheaper case, I personally recommend the Coolermaster HAF 912, it's the best bang for your buck when it comes to cases. Excellent cooling, good cable management, and it doesn't look too bad, either. A big feature I always look for in a case is the ability to run the PSU upside down, so it draws air from below the case. This means it wont interfere with the flow inside the case, such as fighting with your GPU's fans. I can also verify that they do infact honor their mail in rebates.

Now, with the money saved on those parts, I'd invest more into your GPU. The 7850 is a good card, but another step up, and you reach the sweet spot of price to performance. I recommend this card here:

Lastly, you'll need a CPU cooler, the stock ones are pathetic. As others have said, the Coolermaster 212 Evo is the best cooler for the money.

So yeah, with that build, you'll have one hell of rig.
