Actually right now my USB SSD's don't even have an enclosure.
I don't remember if you mentioned whether the PC was desktop/tower or a laptop. If the latter, this is probably infeasible, but if the former it probably should.

Have you considered putting everything you can inside a "Faraday cage". You'd need to make a suitable-sized box out of wire mesh and electrically connect the panels well every couple of inches (solder, soldered braid, copper tape, e.g.: https://www.digikey.co.uk/en/products/detail/3m/1181-X-1-2/111515) and earth the whole thing, preferably with copper braid. You could also fit ferrite beads to any cables right as they come out of the cage, e.g.: https://www.digikey.co.uk/en/produc...xUomCqwqi5ar4RKSQFEasktIgAEyaaHgCwpx4EUA

There are DIY designs and ideas on the Web.

In principle that should cut emissions significantly.
