@MikaChanical, can you double check the mounting holes against the enclosure?

Can you also re-check cable connections for interference?

@daniel , I've checked the mounting holes. They match the enclosure and mounting hardware.

The cable/connector interference is clear. We're all set!

@RevaReviewa, that's a great find! I've notified the firmware team.

The FW changes should be done and out of testing by this afternoon. I'll attach the changes when they're ready.
