One possibility that I think would be cool (but I won’t be attempting anytime soon since I sprung for the 3-year warranty) is drilling out a usb type c slot on the left-hand side, attaching one of the boards from Librem13 USB-C Charge Hack Thoughts? , and then internally routing a cable from the DC output to the barrel jack on the right-hand side to enable charging from either side of the device. With the board with USB data you could even get data working through the port (though obviously no alt-modes). Naturally, we won’t know if this is possible until we have the machine in-hand to see what kind of free space we’re dealing with but having a barrel jack gives an easy path for this hack by providing a simple interface to supply DC.
