So my new 27 inch iMac will be delivered by UPS. Is the cardboard box the iMac ships in also trapezoidal? I'm not talking about the white iMac box, but the tan cardboard outer box. The reason I ask is because I won't be home during the delivery, and that trapezoid is an obvious shape to a savvy thief. UPS always hides my packages on my porch, but anyone that walks up to my front door can see boxes left for me. Thanks in advance!
