I've got the CoolerMaster HAF 932. Bought it last August. I took a look at the photos of the Storm Sniper over at newegg.com. Interior configuration looks similar to the HAF 932. The difference in the interior layout is the fan configuration. The HAF 932 came with 4 fans while the Storm Sniper comes with three fans.
Looks like most of the difference is the exterior of the case.
