Well On carpeted floors is a big one if your tearing down on carpeted floor and in Cotton Socks. Also, main way people whack things is when things are on. In Tech, I was trouble shooting a motherboard while it was out of the case laying on a static bag, and I accidentally whacked it. Yeah it smelled like crap, and acctually a little poof of smoke came from it aswell. You prolly wont whack ram but watch out for motherboards.
