nah youre worried too much. its pretty simple if you do everything step by step with care. the only thing you should avoid is static electricity especially on motherboard and CPU so get an antistatic wrist strap. however, i have never had any problem building pc because of static electricity even without antistatic wrist strap. that case rarely occurs. just treat your pc components like "eggs" or "baby". if you have any question or concern, ask us because we will always here to help you
