Just got my 27 Inch 2.7 GHZ today (the motherboard of my 24 Inch offed itself last Saturday), but, unfortunately, the excitement of the moment was greatly diminished when I discovered after opening the outer shipping container, that it had been shipped upside down. Normally, I like to rag on UPS, but in this case it wasn't their fault, as Amazon didn't bother to mark to box with any directional arrows or related caution markings of any kind.
So far, everything seems to be operating normally, but I was wondering, just what kinds of stress/damage can happen to an Imac when shipped upside down, and in what ways would any shipping related damages manifest themselves?
Also, I guess to take it further, does being shipped upside down automatically guarantee that there will be some form of damage to the machine? I was thinking of shipping it back on principle, but there's no guarantee that the same thing won't happen again, and the thought of having to deal with again the local Mac dealers leaves me cold.
