Right sorry to bring up an old thread again but i'll be changing case soon and like what userunknown has said i dont wanna damage any components via ESD! I bought a wrist strap already but do i just connect the other end to the case? Does the case have to have the psu still in and connected to the mains with it switched off? OR can i just put on the wrist band and connect the other end to the case chassis (unpainted part)?
