For those unfamiliar with the (Open)Pandora, it's a mini Linux PC about the size of a Nintendo DS gaming handheld and comes with controls that work well for gaming. The ARM-based mini gaming system can run Android CyanogenMod, OpenEmbedded, Arch Linux, and Slackware.
The full hardware design files and documentation are now publicly available for non-commercial use. "Thanks to the designers Michael Weston (PCB) and Dave Cancilier (Case), the case and full hardware design files and documentation (schematics, gerber, BoM, etc.) have been opened up for non-commercial use. Whether you want to use it to repair your unit, modify it, create your own 3D printed case or are just interested to find out what's needed to create such a device, that's totally up to you."
More information on the opening of these design files can be found via this forum thread.
