I once was given three older Compac tower PCs. They were stellar RFI
generators from "DC to light". A single Corcom line filter installed
between the AC line cord connector and the line cord did the trick. It was
well bonded to the chassis of the PC and did very little until I bonded it
to the chassis. All these line filters require good high-frequency bonding
to the RFI source.
