Maybe you haven't heard of OUYA? If not, it's an ultra-low cost game console designed for open development. Taking a cue from Nokia's user-3D printed case program, OUYA has partnered with MakerBot to release design files that permit you to develop your own unique case for your OUYA.
Customizing your own objects is the prime directive for 3D printer owners and this announcement presents an opportunity to do so. But there's one problem: the OUYA doesn't ship until sometime this June. Some commenters on the associated Thingiverse "development kit" page expressed their feelings, both pro and con, with most of the cons lamenting the future delivery of the hardware.
Nevertheless, the OUYA will eventually ship and custom cases will suddenly appear.
