I'd meant to respond to this but, apparently, forgot.

There is but there are some caveats which may make it unsuitable, for you. MNT Research sells a few different pieces of hardware which are entirely open hardware with the aim to be entirely repairable and modifiable, even more so than Framework (from what I hear). They publish the full spec.s of every component the machines are built with and you can even buy printed copies of the manual which lays out the spec.s of all those components.

One of the caveats is that they use ARM; on the one hand, that means no need for fans as there really isn't any kind of heat build-up but, of course, not everything is available to be built for ARM (you might know this already and I apologize if anything I mention isn't needed).

The other caveat is that the laptops are a tad chunky (mostly to make rooting around in the innards to swap parts and fix things easier); some people don't mind that but I figure I ought to make note.

The new one they're working on, but haven't released yet (they ship the earliest in July, though, so coming up), are somewhat more slim, though: https://www.crowdsupply.com/mnt/mnt-reform-next. But it's really a matter of relativity.

I'd heard that they were kind of slow but that the newest CPU they got for the upcoming device reaches levels comparable with other laptops? I'm very much out of my depth in that area, though.

Lastly, I'm going to go out on a limb and assume, based off your instance, that you're family and, so, mention that the CEO is genderqueer (Mastodon account at https://mastodon.social/@mntmn). So you do get the added benefit of supporting a Queer-owned business which I don't think even Framework offers.

I don't own anything by them so you may want to read up on some reviews or lurk forums, first, but it definitely is as committed to right-to-repair and interchangeability/upgradability of components and also deeply committed to open-source.
