As far as I can see, the T440p is the latest Thinkpad to support Coreboot/skulls.
If I wanted something newer (say, something from 2019-2022 or so) under $400, what could I even get? I want to run my own choice of linux distribution on it, so most chromebooks are out of the question (also I’d like something more powerful and upgradeable).
Thanks.
Starlabs.systems models support Coreboot.
There are many Chromebooks with coreboot as well.
I did go over mrchromebox, and might actually go this route. We’ll see if there are any newer chromebooks that let me replace chrome os with linux by the time I get to purchasing one
