Apple stores to sell all Mac Pro configurations and parts

I just called the Northshore Apple store here in MA. I asked if they carried any of the new ram for the Mac Pro. I was disappointed and excited by the response. I was told not to expect any of the extra bling to be available in-store for another month. However, they will be carrying all Mac Pro peripherals as well. We’re talking video cards, Superdrives, SATA internal disks and RAM. They will offer any configuration on-site or you can purchase al-carte. This might all be B.S., but the guy seemed pretty confident about it. I did not get the impression that he was just guessing. This is really going to hurt my bank account.
