Based on not just one but two Adafruit designs we've combined the Beagle Bone case with the clip together Raspberry Pi case along with a couple of extra alterations like the hinged lid and improved dragon claws (with inspiration from Deferred Procrastination). The result is a sturdy clip together case with a hinged lid that will fit your lovely Beagle Bone Black. We've just added it to our collection at http://www.phenoptix.com/products/beagle-bone-black-case-clip-together-enclosure
