Any plans to sell a full laptop kit minus mainboard? I have a Framework with the 11th Gen CPU (that I love very much) and I like that there is an upgrade path to the 12th gen CPU, but afaict that would leave me with an 11th gen mainboard that I can't turn into a second laptop easily and would be hard to sell for the same reason.
Considering you'd like to buy both a complete laptop minus the main board (to put your existing main board in), and a main board (to upgrade your existing 11th gen), I'm sure there's a solution we can find here...
People put the mainboard in a 3-d-printed case (the plans for which are given away by Frame.work) to make a tiny desktop computer (like a NUC), so a mainboard would sell.
