A snug fitting case for the Arduino Uno with screw board mounts and a snap top. Shields may be installed over the top of the case. There are four holes on the top to view the four LEDs on the Arduino board. These holes can accommodate Bivar PLP2-250 light pipes for a more polished look.
The screws for the Arduino board are #2 x 1/4" thread rolling screws.

Update 11/20/15: Added hole on top for the reset button.
