I can still hear it a little, but it's definitely stronger when connected.

It's a home-brew, but it's a good Antec case and all the various and
sundry hole-fillers are present.  There are no neon lights or bubbler
setups.  :-)

746 et al are all connected to the station ground outside the radio
room with decent, if a bit light, copper braid.  All wires also come
in through Alpha Delta TransiTraps which are grounded to the same
ground rod.

Not sure what you mean by internal shields.  Empty card slots have
fillers, filler around various ports is in place.
