I've created a new case for the Raspberry Pi, primarily to be used as a mediacenter box.
Similar cases have been designed before, but I wasn't 100% happy with those available yet, so I went on and created my own one.
Vesa mounting plates (for 100x100 or 75x75) can be added to the case.
This case is assembled using 2.5x16 SPAX screws.
The 4 screws connect the top part with the RPi and the bottom part.
Another 4 screws would be required to attach the vesa mounting frame.
