Do open up and take a look. Do take photos. Do share. :)

I can see that the back two panels have been removed and replaced, but nothing obvious has been done on the inside.  There are two SMB connectors on the main board that don't have anything plugged in, but there's nothing obvious that they'd connect to.  Does any of that tell me something that I don't want to know?  It's going to be a long wait till Monday.  =)
