andystanley brought up some good idea's. That CM HAF XM he mentioned is new on the market and Cooler Master gave it all the latest and greatest goodies. And as far as gaming goes an SSD is always nice to have when your loading up levels (maps) in any game. Gaming off an SSD is the only way to go imo. Give this build a look and read some of those reviews.
