Motherboard with keyboard (black) - best for standalone operation

Motherboard only (red) - best for integration in to original case but also can work with USB keyboard / joystick

Keyboard only (white) - can by connected to any ZX project or if you need away from motherboard

This board specially designed to original ZX case. But can work standalone on desk because have integrated keyboard.

Keyboard switches distance is same as ZX rubber / Faceplate, I have no idea how it can help, maybe if you design own case, I could have designed the keyboard differently, but I took care of this option.

anyway, it won't fit perfectly and it will be a bit of work with a file.
