One (often overlooked) standard for the chassis earth ground is that it shouldn't be able to be loosened from the outside world. This eliminates standard screws and bolts. What is a good DIY solution?

why? if someone yanks the power cord out and the strain relief pops, then the blk and wht wire will be ripped loose before the grn wire, thus, the chassis loses power before the grn wire is ripped,
