Looking for ideas here

Small (mATX) cheap (is better) OTT(not the clean lines I prefer) case for an air build of a 2600K hd5870 MIVG

Kinda lan party but if it has loads of plastic and looks like a transformer better still.

I might even paint it bright colours or I could go for a military look.... it's for my Boy

Pics or links please folks as I have no knowledge of cases like this
