Hi All, I am about to install a Firewire host card into my P.C. There seems to be two schools of thought on electrostatic discharge and the harm it can or cannot do to a P.C. I have been told that an E.D.S. wrist strap is essential by one school and not necessary by another. Before I take the back of my P.C. is someone able to advise, please? If a strap is essential can anyone advise where I can buy one. Many thanks.
