Reproducing what they have aside, you can also modify any aspect of it by remixing their designs. The most common example of this has been custom keyboard layouts (ergo, split, etc).
Framwork is usability and performance first, openness second. MNT is the other way around.

https://www.clockworkpi.com/home-uconsole is another great example of a machine I've seen people mod into all manner of special-purpose device that wouldn't work as well with a used business laptop.
I agree, it's probably a better idea to stick to something that was sold in high volume - if only for replacement parts down the road. If one really needs low power, an older M series Mac would also suit the bill (sacrificing many of the other benefits of course).
Eventually those Thinkpads will run/wear out. The hardware designs for a [pretty much a Thinkpad] will be a good thing to have then. Let rich nerds looking for bragging rights support development for the future; call them patrons.
Also, they will sell 6 of these, it's not an environmental concern in any way.
for instance, some intel cpus with ME could be hacked from both built in ethernet and wireless OUT OF BAND. The ME was accessible in commercial laptops, but since it was not "supported" the end user had no way of even disabling it.
Its over engineered in some ways and woefully under engineered in others. Any real effort in making it more performant or trying to extend it's life will just generate more additional ewaste than it will save by just reusing existing hardware.
The motherboard is modular and the compute part of this is replaceable, it's sort of the whole point.
The modules are mostly compatible between all of their products: MNT Reform, MNT Pocket Reform that are available now and the future MNT Reform Next (a more streamlined laptop) and the MNT Station (mini desktop pc).
Also there's a user story out there where a laptop is a mobile terminal and the actual processing power happens remotely in the cloud. With modern agentic workflows and how fast they're changing it makes sense to optimize for longevity on the client hardware.
It's like framework laptops, but EU based and without the drama of funding a fascist developer.
