Nope, because of having 3 nav keys about the arrow cluster there is no aftermarket cades I am aware of that it would work with. If it had the normal 660C layout or even Varmillo's V68 layout you could probably jerry rig one of the metal cases for those to work with a one 2 SF. As it is the only way I could think of getting it into a metal case would be to desolder & get rid of the Pg Dwn switch, then putting it in one of those alum cases for the 660M if you can find one.
