On August 17, I ordered a custom iMac from MacMall - the 2.9GHZ model with additional RAM (16GB) and the 256GB SSD. Today I was notified that it shipped, so I checked and saw it shipped from Memphis, TN. I wondered why it didn't ship from Cali, so I called McMall. At first, their rep told me that they (McMall) have a plant there and that their tech installed the RAM. I told him that this would clearly void my warranty; that Apple makes that clear. He said, "Let me check" and quickly changed his tune and told me that it was in fact customized by Apple and then shipped to their plant. I'm concerned that he gave me two different answers. Here's my question: When I get the iMac, is there anyway to ensure that it came directly from Apple and that only Apple installed the RAM and SSD? What signs can I look for on the box itself and within the iMac itself? Thanks in advance.
