I'm going to be shipping out a PC soon. Fedex seems to charge a fortune to pack+ship it. Any advice how I should pack it? I was thinking about using the case box. Then double box it with a lot of layers of bubble wrap around it. Should I bubble wrap the computer itself or wrap it around the first box? Also, if I bubble wrap it, plus a double box do you think it would prevent it from damage if it's tossed around?
