From a timing perspective, I got totally lucky. I happened to be there twice in one day, and just got lucky that he had dissembled the machine a few minutes before I walked in (he was still putting it together with updated parts when I was at the counter). Prior to that, I had looked everywhere for weeks (it was supposed to be for Christmas!) without any luck.
Patience and luck in my case. And the Micro Center has earned me as a loyal customer.
