Do you have time to build something partially from scratch? I could see repurposing an old laptop, disassemble it and make the screen face outwards with the board affixed to the back of the screen lid.
Might take some creative routing with the internal display cable, but I’ve taken apart tons of laptops where this would be doable, especially after you’ve discarded the plastic chassis
Though you’ll still need a frame of some kind, unless you like the “raw-tech” look
