Netbox: Devices not in racks

Netbox users, how do you handle devices that are not in a rack? Examples:

• Access switch and IAD mounted on wall in telecom space (wiring closet).
• Smart PDU sitting on floor near a few racks that are in a rack group.

The only idea I have so far is to create a virtual / pseudo rack. Perhaps with a -X suffix on its name to denote that it isn't physical rack.
