TERES-I Do-It-Yourself Free Open Source Hardware and Software laptop with ARM64 and x86 processors. Comes as a kit or a bunch of spare parts. FOSH/FOSS. ARM64, x86, MIPS variants. Can be upgraded piecemeal. Definitely runs Ubuntu and Android, can probably run other ported distros with a bit of work. Has all of the features and components that you'd expect, from wireless to a built-in webcam. Of course, you can probably leave out the stuff you don't want.
Give it an identifier or serial number for a Compaq, Dell, Fujitsu, HP, Insyde, Phoenix, Sony, or Samsung laptop, and it'll generate a backdoor passcode to get into the system settings.
