what if create a frame design where the mainboard goes vertically on the righe side.(15,6´)
(Use the typeC directly for connection) but gain more space on the left side: for 1. usb hub internal.
, 2 bigger battery., 3., gpu-board and battery
cover with keyboard: make it separated band line for keyboard and touchboard with the option to move them up and down. Design with the similar concept as on this picture, but Im talking about the touchpad
