> Or just buy a Thinkpad second-hand and Libreboot it yourself.
Not any ThinkPad, only the X60, X60s, X60 Tablet, X200, R400, R500, T400, and T500. And there's also the MacBook 1.1 or MacBook 2.1.
For clarity, it's likely never going to be possible to get a newer computer than the X200 to work with LibreBoot, and anything newer would only be marginally so. See the Libreboot FAQ:
