Hi, I am in the process of building a lab power supply which is to include some USB ports.

I have no problem with 5v rail and GND but can I leave the shield just hanging?

The box itself is wooden so tying it there would be of no benefit.

If you don't use USB data signals the shield is not needed. If you are running a complete USB hub or something similar, the shield should to be used minimize radiated interference.
