I mention this as while tape or no cover at all might be fine for home, knowing Jacob is into Free-mo then if he's at a meet then I'd caution that the meet might becomes a workplace under some sort of law and the terminals would need to be covered properly.

I build 'booster boxes' out of plastic Home Depot/Ace/etc style 16-19" tool boxes. They have a floor of 1/2" Baltic Birch with a Mean Well power supply and a Digitrax DB150 mounted inside. I have two sets of Anderson Power Pole plugs with DC on one side and DCC on the other so that I can power DC at home and be Digitrax compliant at a Free-mo setup. I have a a 92X25MM AC axial fan and vents built into the box to provide cooling.
These are used with the lid latched closed (ventilation described above) so I would imagine a simpler cover would suffice. I can attach an exterior label requiring AC power to be removed before opening as well.

That's an interesting factoid about the hole diameter and RF wavelength Alan. Another tidbit of knowledge to tuck away.
My SMPS, and the one I used for the charging station at work don't have holes but slots, just like your MeanWell for the accessory bus (mine is the same style as yours but different model NES instead of SE, they were a good deal at the time). I wonder if I should read the specs for any derating, the one at work I mounted upside down under a shelf; it's still horizontal just upside down.
It sounds like you've got everything covered Jacob. Being inside the portable power distributor "toolbox" you probably do only need something simple to prevent something accidentally bridging the mains terminals. I'm surprised that the supplies didn't come with a clear plastic clip-strip for that purpose.

I was surprised too but I imagine the target market for these is someone with enough electrical experience to know how to build a proper cover.

Mount horizontal and provide ventilation.

IIRC the PWR-56 requires a horizontal mount as well. I have to assume this is significant.

If I was to get a power pack like the one in the post which one should I get. I am unsure on the amp.
