Alienware Motherboard question

[LastLivingSouls]

I'm looking to buy this Alienware R9 motherboard/case off ebay.  One of the photos shows what looks like a missing "socket" that the USB plugs into around the pins (below the black one, right side middle).  Is there supposed to be a socket there, or is this something different?  If the socket is supposed to be there but isn't, what effect would this have? What it just be a "wobbly" connection (it appears all the pins are there), or would the header fail to work?  Any thoughts on this would be helpful.  Thanks

Why does this manual look not correct. hhmph

Looks like a USB3 front panel connector-- those plugs are super tight so I wouldn't be surprised if a careless past owner had pulled the socket out of the board accidentally. There's another header above it though, so unless you need 4+ front USB3 ports, you'll be fine just using that.
