Has anyone ever mocked up a 12v muffin fan (aka - computer cooling fan) for moving air inside a camper, campervan, truck cap, etc.?

I have acquired a 200mm Antec Big Boy fan that has a 3 speed switch. I'm trying to figure out if I can use it in my van so I'm looking for some brainstorming ideas from others who have tried.

Thanks for any ideas! Pics would be great!
