I normally just run my secondary ground wires to the closest piece of structural metal I can easily get to. Wait a min here. Correct me if I am wrong, but don't most motor mounts use a form of polyurethane to absorb vibration? If so then the polyurethane would work as an insulator, stopping and conduction of electricity between the block and the frame. |

The urethane bushings are on the topside of the mount structure, between the mounts and the motor, and primarily are there to absorb the flexing from torque that would otherwise weaken the metal. in the case of a PC case, the spacers don't insulate at all, but simply prevent the screws from chewing up the board. |
