Ask TheVerge, recommendation for case/barebone

Hi, I just got Radeon HD 5870 Eyefinity 6 card for some "payback" deal.

Eyefinity6_5870_3_medium

Since it's pretty good deal for me, I want to make a good use of it. I'm planning to build a custom rig around it, so I can play some games and stuff in my living room on tv. Not going to use for multi-display thing.

Now guys, please recommend me some cases or possibly barebones (of course which can house that big display card) that are smallest possible size.

Thanks
