@mntmn Assuming my earlier comment wasn't too far off the mark. Perhaps it would be worth while for you to reach out to the guys over at: https://www.powerpc-notebook.org/en/ . Right now I think their plan is to design a motherboard to drop into the same chassis used by the KDE slimbook. If you are doing what I think you are doing, it would be much better for them to design to the new standard you are creating.
