[sdiy] plastic front-panels?

[harry]

You need to determine what the frequency of interest is...

Low frequeicies are primarily coupled by magnetic fields.  Ferrous
metals are the best defence... the thicker the better. Mu-metal
(a nickel cobalt alloy) is the best... see Advance Magnetics for into.
Its ungodly expensive but the best performer.

At higher frequencies... the coupling is more capacitive, and any metal
can stop the coupling, aluminum and copper are both very good.

higher still... and even the metallic paint might work well.

I would still use a metal box for any audio gear... preferrably steel... but
I do most stuff in aluminum without too much trouble.
