My new Dell tower's front module for USB/headphones/mic is not anchored!

Sorry, I don't know what to call this thing: http://imgur.com/jgsWO

But it has the jacks for USB, etc., and is accessible from the front of the tower. But it was not mounted correctly; it's just loosely sitting in the mount, and gets pushed back inside the case if you try to plug anything in. http://imgur.com/WK37U Do I need to get something to mount this thing properly? I'd prefer NOT to have a tech support person come out to do this...

Edit 12/12/12: finally decided to have the tech support guy from Dell come out. He replaced the module with a new one. Apparently, the old one was missing a little clip of some sort. The guy was very quick and helpful. Thanks, Dell Tech Support!
