Are you sure you want an ATX case? If you don't plan on doing a tri-SLI/CF setup and don't have a bajillion optical drives/HDDs/SSDs, you should consider an mATX case.
If you want something "gamer-looking", you should check out the NZXT Vulcan. It is an older case, but the airflow is extremely nice for an mATX case (mesh side panel capable of fitting a 200mm intake fan, 2x 120mm exhaust fans at the top, 1x 120mm front intake, 92/80mm exhaust), has two built-in fan controllers so you can rev up your fans when gaming and turn them down when just websurfing, and a switch to turn the LED lights on/off.
If you want something more elegant, you should check out some Lian Li or Silverstone mATX cases on Newegg. If you need ideas, check out this thread: http://www.overclock.net/t/541767/club-for-those-with-beastly-matx-itx-rigs/3240_40
