MOTM

I just built myself a cabinet for my MOTM system.  Does anyone know a good
way to non-permanently fasten a panel to the rear?  It's usually easier to
get to power connectors from the back and I don't want to paint myself into
a corner by nailing that panel down.  The cabinet is made of 3/4" birch
plywood and too soft to use screws more than a few cycles.  The back panel
is 1/4" birch plywood.  I couldn't find any latches at the hardware store
that seemed like they would work.  Any suggestions?
