This utilizes one of the M19 threaded ports on the FormD T1 to add 10 Gigabit Ethernet using the Innodisk EGPL-T101 M.2 module.
Use M3 screws to attach the ethernet port to the gasket.
Make sure the screw head does not protrude past the plastic, otherwise you risk scratching your case during final installation.
