@thomasfuchs There's not much about these cases out on the net but I did find this vcfed forum post about them (including some posts by @vwestlife ): https://forum.vcfed.org/index.php?threads/looking-for-very-special-portable-pc-with-color-monitor.80071/ It looks like they were sold as standalone cases or used in white label builds. This one has a logo saying APR and a manufacturer label saying "America Portable Research". The CRT looks original, no idea about the motherboard until I figure a way inside without breaking any plastics. There are no external screws...
