hi, i was wondering,how is a anti-static wrist band used? it says to attach the alligator clip to the non painted part of the case, is that the back of the computer? also, when and where do i have to touch with my hand? one last one, when you completly take the case off, and there is not case, what do i do then and do you neede to use a wrist wrap if it is the first time the part has been used, like when you are first putting it together.....sorry if too many questions.....THANKS
