Hello there, I'm traveling to NYC next February and I'm planning to get a Mac Mini with the following configuration: Fusion Drive and 2,6Ghz i7. (I will upgrade the RAM later). So, as you may know, this isn't the standard configuration from Apple. Here's my question, can I go to the Apple Retail Store and simply pick up my Mac with these features? Or I've to wait to the next day to get the Mac properly configured? I'll be in New York for just three days, and then, I'm moving back to Uruguay. Thanks for your time, have a nice day!
