using the non-ferrous casing from Home Depot. I was able to take off the spring-loaded outlet covers, and the whole thing looks like a million bucks.

OK, now follow Al Sekela's advice and break the ground loops the way he suggests. This is an easy improvement that you'll appreciate.
Also, you may not realize this, but there is a putty colored sheet material that electrical places sell that's used to create more of a waterproof seal (I think that's its use) for these boxes. It's cuttable and malleable. You can use it inside the bottom of the box by lining it to get some additional mechanical damping.
You may want to experiment with the ceramic cover plates to see if you like their mechanical damping effects (as opposed to the pot metal plate you have). I've used both kinds of plates and settled on the ceramic, but that's just me. Nothing hard and fast here!
FYI, these boxes also benefit from spike/cone footers or isolating footers too. Again, mechanically damping the case from the floor this time.
formed by the outlet back straps and the metal box. Replace one of the two fixing screws with Nylon, and slip a Nylon washer between the outlet and the box.
The outlet back straps and metal box form a one-turn transformer with the hot and neutral AC wires that pass on either side of the strap. Current delivered by the outlet causes current to flow through the back strap and box unless you break the loop.
I briefly looked, but who carries nylon screws of appropriate size?
I haven't looked recently, but I would not be surprised if they don't stock them anymore. Home Depot seems to be reverting to their old, repulsive habits.
There are plenty of on-line sources, or you can check with your local fastener supplier. Most larger cities have at least one company that stocks and sells a myriad of bolts, nuts, screws and similar hardware.
What you want is #6-32 by 1-inch binder head or similar.
