Your chances of everything being OK are probably at least 90 percent. That explains why several people can post "I did it and I didn't have a problem."

That said, I wouldn't take the risk. To an experienced baggage handler, the shape, weight, and weight distribution (toward the center; feels different when you rotate them) of your boxes would be like a flashing red neon sign reading "Computer Inside." The great majority of baggage handlers are honest, but every occupation has its bad apples and a computer can be very tempting. Go with a shipping company.
