Hi guys. I recently bought a Neo 75 and decided to go with Kailh Box Navy switches and GMK Pharaohs. When I came to build the keyboard, I installed the switches and secured the cover down. When I came to put on the switches, I found that they did not fit. The side of the switches rubbed hard against the aluminium case and did not move smoothly. I have tried the keycaps on another build which uses Gateron milky yellow Pro switches, and They seem to fit okay. Is this a problem with the Kailh Box Navy switches? If there is a compatibility issue, what should I be looking for in the future?
