To remove the PCB, you just have to undo this screw. It is a flathead screw, secured by a 6 mm nut on my keyboard. It may be slightly different between models, but don't expect anything exotic here. It was handthight on mine, so I didn't even needed any tools to loosen this.

Your keyboard is now fully disassembled.

To remove keycaps, pull the keys upwards. I recommend using a wire keypuller. The process is the same as with any modern mechanical keyboard.

To assemble your keyboard, follow the guide in reverse order.

My keyboard will need a bolt mod in the near future, I will plan to make a guide on that too. Keep an eye out for that.
