Crazy question folks, but can anyone tell me the physical dimensions of the 21" and 27" iMac boxes? i.e. Not the actual Mac itself, but the cardboard box the whole package comes in. I'm going to the States in December and want to bring back either a MBP (which I would take home as hand luggage) or, if the size of an iMac isn't too big, possibly a 21" or 27" iMac, but the physical size of the box will be crucial. My return flight is from Washington to Hearhrow (first class), but I have an internal flights from Florida to Washington first, then another internal flight from London to Glasgow, which means the iMac will probably have to go in my hold luggage for the return leg.
