A broken GRiD 1550SX laptop like the ones used in the movie "Aliens" was converted to a Raspberry Pi and Teensy laptop. Simon did an incredibly clean conversion that includes using the original keyboard plus the IsoPoint roller bar mouse. I assisted by writing the Teensy LC code for the keyboard and IsoPoint. The IsoPoint precedes PS/2 touchpads that eventually became the standard for laptops. The IsoPoint uses rotary incremental encoders which the Teensy converts to USB. The Teensy code can be found on Github (https://github.com/thedalles77/USB_Laptop_Keyboard_Controller/tree/master/GRID%201550).

Very cool project.
An other approach with such a huge shell would have been to mount a mini ITX mobo and put in an i10 multicore to make a real racer, a wolf in a sheeps's clothing. Some flat LiPos and a BMS, a touchscreen and integrated universal AC/DC power supply, PCIe SSD. oh yeah...

Or a NUC board: https://www.intel.com/content/www/us/en/products/boards-kits/nuc/boards.html
