Rikki,
I am no expert, but was recommending something
like the mini tower size listed here: http://www.xoxide.com/buy-computer-cases.html

Frank suggested the small form factor(6 pack)
size, which is excellent, but,I think, is
more expensive and limited than the mini tower. http://www.tomshardware.com/2005/01/05/casing_out_microatx/

Either one is still small enough to be practical for live gigs. You would, of course,need a nice, small flat panel monitor.
