Here's a good case, the Corsair Carbide Series 400R Graphite grey and black Steel / Plastic ATX Mid Tower Gaming Case at newegg. HERE - http://www.newegg.com/Product/Prod [...] 6811139008
This is probably one of the best for cooling - NZXT Tempest 210 CA-TP210-01 Black Steel / Plastic ATX Mid Tower Computer Case

Not sure if you're looking for something striking or plain Jane, everybody has their preferences, But here's a COUGAR Challenger Black Steel ATX Computer Case with 12cm COUGAR TURBINE HYPER-SPIN Bearing Silent Fans and 20cm LED Fan

Thermaltake is a good choice, Thermaltake Commander Series Commander MS-II Black SECC ATX Mid Tower Computer Case

Anyway, that's about 15 pages worth of newegg I thought would fit the bill depending on your tastes. My choices would be the Corsair Carbide 400R, then the NZXT.
