It is still a case, albeit skeleton style but still a case.  If you haven't looked at manufacturing methods yet I would recommend waterjet, I am not sure if CF can be laser cut.  Even if it can I would venture to guess it gives off toxic fumes similar to acrylic when laser cut.  Also, from other materials I have seen both laser and waterjet cut, I much prefer the edge quality of the waterjet.  However, the roughness on the cut edge of laser cut plates greatly adds to the ability for the switch to grab a hold of the plate.
