 If I understand you, you mean something like this?

Please note I didn't add the dadoes nor vents and kerfing for the curved
sides.

There's really not a lot holding the PCB, about 0.6mm due to the PCMCIA
Connector being so close to the edge on the right (as can be shown in
images 06 & 07 which has the front plate hidden). Maybe pieces oriented
sideways would be best as they could provide more support width.

Also, with the bottom plate exceeding by 3mm all around this may make it
hard to insert/remove the SD card, the plate might need to be notched.
