Can I put a Dell optiplex 360 motherboard in a new case?

Hi,
I have a Dell optiplex 360 that I picked for pretty cheap. I would like to turn it into a gaming PC. I tried to install a ati Radeon x1650 pro gpu, but it wouldn't fit. I have a full atx case and a micro atx case on hand. Can I put the motherboard into either?
Thanks a bunch.

That is a BTX Computer Motherboard so it wouldn't fit in full atx case or a micro atx case.
