The MNT Reform[1] is an interesting option, although it's not available quite yet. One thing in particular your post made me think of is the fact that they've changed the battery to a bunch of 18650s that you can swap out at your leisure. Also, it's all completely open with schematic and source code online, and they mention that if they make a RISC-V board, it'll fit in this one's chassis.
