My first iMac 27" I7 that I purchased as a new unit was sent from shanghai. Within 24 hours the hard drive crashed. I received an RMA from Apple, and sent the unit back to Elk Grove, California. My replacement was supposed to ship out when FedEx scanned in my tracking # that Apple provided. Instead, it took an extra 3 days and I was sent an email notifying me of a delay in my shipment. The replacement shipped today except it was sent from Union City, California. Does anything think that I may be getting a refurbished unit that someone else returned? It seems odd that it's coming from California this time. As soon as I get it, I'll be checking the build date.
