RAM is not compatible. Here are other recommendations.
1. Switch the 4350 with a 6350 (I made the same choice for the 4350 originally, but changed to the 6350 because it performs better, especially for gaming.
2. Try and spring for a slightly better MoBo (such as this one http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
3.Go for a 550W or 600W PSU so you have room to upgrade in the future.
Very nice build, and very similar to what I am building currently. Good luck with it
