i also considered the @doc solution...but then a problem might be getting the connections and buttons through the casing of the desktop casing.
plus the pc casings that lay down are rare it seems, cant find them 1 2 3.
edit:
what about this one?
but if i buy this, i need the tools to cut out the inside and cut some big holes in the outside...
so the backside of my current projector can fit for controls...and hole for the projection ect...
