I like the Silverstone Temjin 5 (SST-Tj05) or the Tt Eureka (the Shark is basically the same case if you need something more ricey). The new Antec NineHundred should be a decent gaming case but it might be tight for long vid cards - there is one or two threads here that have links to lists of cases that can handle the long cards. Then there is the XClio Windtunnel (see the thread on it here for links). And the original Coolermaster Stacker (STC-T01). Or perhaps the Aerocool Zero Degree (this one may be fussy as far as handling the long vid cards - at the least you'll probably have to arrange the drives to accomodate any really long cards). Or if you want a serious looking case - the Chenbro SR10568/69 workstation cases might do it for you. Any case that can handle the EATX mobos should have no problem with the long vid cards at all.
But not knowing what you plan to put in it, etc. it's hard to target a response.
