A faraday cage is a volume that is surrounded by conductive material in order to shield that volume from radio waves. That’s not what you need to avoid static damage to computer components. What you need is adequate grounding, so that no static electric potential builds up between you and the computer or any removed parts of the computer. In dry weather, static can be generated simply by a little rubbing together of parts of your clothing. If you want to be extra-careful, you should (1) make sure that the computer is unplugged (2) connect yourself to metal on the computer chassis—use a wrist strap [from computer store] or simply tape the uninsulated ends of a piece of wire to your body and to the metal on the computer (3) place removed parts on a conductive surface (cookie sheet, for example) that is also connected by wire to the computer chassis. Being connected to the computer by metal assures that there is no significant voltage between you and the computer. If you’re willing to b
