Do you sell any accessories to secure the mac mini to the shelf? The scenario I have in mind is that of a flight case rack that is regularly transported, so the mac would need to not move around in transport. Thanks.

The faceplate shelves come with a clamp bar that holds the equipment in place. Unfortunately because the faceplate is magnetic is not possible to secure this completely. Although the magnets are strong, we could not guarantee it will not slide off if the flight case has a sudden impact or movement.
