actually you could just go down to a local metal shop and they would bend and aluminum case for your dimensions imho for the
price it would take to get a unit from Sweden

not a big deal they make boxes out of aluminum for all sorts of uses..anyway would not be hard to do where I live they'd even tap out the screw holes

also you would not have to do aluminum you could do a pexiglass arrangement like the MARS prototype unit has that in fact would probably be easier to find someone to do
