It's very important that machine hardware be kept in a proper state. This means that all connectors should be screwed into the machine where possible. The cables should also be tucked out of the way so that they don't get accidentally tugged. Power cables should be connected to a power bar mounted on the underside of the table or desk. Ethernet cables should be connected to the nearest ethernet transceiver, also mounted on the bottom of a desk. All slack cable should be coiled up and cable-tied to keep it off the floor, so that the floor can be clean. Finally, laptop drop cables should be kept nicely coiled, and clipped and velcroed onto a desk.
