 OK, if you're building, you will want some extra parts ordered up.

M4 x 16mm pan head security torx tamper resistant bolts (14mm+ is fine)

Rubber feet (D30x22xH15)
If you want to have this one on the table, some rubber feet will go at the bottom of the backbox with an M5 bolt. You can also use adhesive versions. Grooves in the bottom of the box will support up to 30mm in diameter.

Cabinet draw tubular 16mm lock
This will be mounted on the door. I may do a variation with an electric solenoid that can use a pin from the screen to unlock so keys will not be lost. I will create shims for different-sized locks to work with the door. NB Door design is still pending.

Will also be looking into actual 16-pin connectors and alike for a soldered finish rather than push pins that are more likely to fall out. 
 Oh, and:

Female threaded heat set knurled embedded insert nuts, M4 x 6mm L x 6mm OD
Using a soldering iron, these are heated up and pushed into the back box for better attachment of the facia.

Secure the ATM when desk mounted.
