Hi Steve, This is good to know. I was just wondering, however, what happens if you happen to have a good charge on yourself (maybe from those nylon underwear) and you equalize the difference through an earth point on your unplugged computer - is there any chance this charge now across the earth rail (that is now not connected to earth so not neutralised, just balanced/evened out?) can affect components connected to this rail? Or if I now plug in memory that is not at this same charged potential can it possibly be damaged by the charge now on the earth rail? I guess I don't understand where this charge goes to if you are not earthed? Can you offer insight into this?
