Hey, I'm going to be building a PC very soon but I'm concerned about static electricity. Some people say not to worry too much about it but just don't stand on carpet or wear wool clothes, and some people tell me to have one hand on an unpainted side of the case. I can't get an anti-static wristband because they're out of stock for the store I'm looking at. What are some tips for avoiding static electricity, or should I just not worry about it?
