What kind of fan for a light hood?

I need to cool a 400W HID light for use in a small cabnet, and know i need about 180cfm, but what I don't know is what fans work and what the pros/cons of each type are.

I'm leaning towards an inline fan of some kind but i'm not sure what'll work, either a centrifigal fan or one of those "booster" fans which I've found rated at 180ish cfm. The booster fan I speak of is basically a stiff piece of ducting with a fan inside. If there is another type of fan that'd work I'm all ears.

Hmm... sounds like it could work, I was told by the dude at the hydro store that they were ubor loud. I'm gonna have to go in there with like $200 cash and show him I have the money for whatever fan I decide on but that I won't buy them without first checking them out. Last I was in there he didn't wan't to plug any of them in, then again they just changed ownership.
