I'm loving my Samsung 840 SSD, couldn't be happier with it. I was looking at the CM 922 as well but ended up going with the Corsair 400r, but that's just because I prefer simpler looks. Very happy with the case as well.
Your original build will do just fine. You could save some money and opt for the 7970 Radeon instead of a 680, but it's not that big of a deal. You will prolly save some money if you do though.
As far as the cpu cooler is concerned, yours is just fine too. The hyper 212 evo is a great cooler for the price, but yours *is* better. Not 50+ dollars better, but it is better. So, you could save money by changing parts out, but nothing wrong with your build.
COOLER MASTER Hyper 212 EVO RR-212E-20PK-R2 Continuous Direct Contact 120mm Sleeve CPU Cooler Compatible with latest Intel 2011/1366/1155 and AMD FM1/AM3+

I really like the case I chose (still in the mail! ordered my parts today ), I'm pretty sure it's the same price/similar to the CM 922- The corsair C70. the white one is on sale 40$ plus a promo code on newegg got mine got 80$
