Serial port header?

[Agent Smith]

I want to get this motherboard and it says it has 1 x serial port header. How do I go about setting up a serial port? Is it a card that I must buy? Or can I somehow add the serial port at the back of the case with the header? I don't think the faceplate would allow that though.

If your talking just a standard serial port. One of these.
