This acrylic Arduino Uno case was designed by the amazing guys from Seeed Studio. It is very sturdy and feels solid in hand, It even has an external cutout for the reset button. What I like about this enclosure is that the I/O are open to using it with male jumpers but even more useful it allows you to add your favourite shields with no problems.
