ddr3 1600 cas 9 is equal to ddr3 1333 cas 7...so save yourself some money and just get 1333 or get some better 1600 with cas 7 or 8....Higher the speed the lower cas you want. Good choice on the case by the way. I always recommend it. White is available is asia only so i'm guessing you are in the right area. Rest of it looks ok.
