ok so i've created corner-pieces which will need to be 3d-printed, they contain slots for the PCB as well as for upright 1.5mm 3-ply sides. the far corner near the PCMCIA eject button needs some work / rethinking because there's a cut-out in the PCB.
the cut-out is basically too far back, and that's lack of iterations / planning on my part - i'm not doing another revision of the microdesktop PCB now, not at this stage, so i'll work something out.
