Can’t speak much on that, but I can tell you that I worked on the computer of someone who used high contrast settings to help them see the screen better and after visiting 3 or 4 major websites it was clear most don’t account for background gui changes and will use less code rather than forcing it, which leads to white on white or black on black text. Part of why I was there was it was getting worse, and so they got a 55" TV as a monitor, which allowed them to go back to standard windows appearance and avoid all the nonsense.
Something as powerful as an M3 at the very least could be used as a folding@home client. Other suggestions would be a rendering farm machine, a retro emulator for higher end consoles like PS3+, or part of a carputer since it’s got GPS and is quite efficient.
