It looks like the Cubox isn't open. At least, it fails the 10 minute rule. I couldn't find the design files, beyond pdfs for the schematics of the "upper" and "lower" PCBs (which don't meet the criteria of being open) and nothing for the main board.

It really isn't open hardware... but it's pretty much the same cpu/chipset and if you're fiddling with software, it's a much better option price wise. That said, TFA's open laptop really isn't so open either, considering the gpu/accelleration abilities are locked up. You give me open hardware with open drivers at something resembling cost competative, then I'll take notice.
