The only difference between the open-pc and the Penguin Wee was branding. The
open-pc came with an old custom version of OpenSuSE that was branded Open-PC.
It was meant to be a more libre solution. It wasn't ever going to comply with
FSF standards though. This was not our doing. We only took care of the
hardware.
The most recent version of it would be here:

Though even this is an old model... although still technically available. The
newest model would be the v3 model here:
