My modded switch lite with new shell and joycons! Got these from aliexpress since the original shell was cracked and the joycons had some dead zones. Whole process took about 3.5 hours (with child interruptions). I had some pics of the soldering but seem to have lost them.
Easy, pay someone $$$ to do it lol…
Less jokey, you do need reasonable microsoldering skills unfortunately.
In Australia I paid someone $150 to do mine including the pi chip.
