Are you talking about where the ports and connectors show through the back? Or are you talking where the pci slots are located near the bottom?
You should of got a plate that came with the board you just pop out the one (if any) on the case and click the one designed for the board in place. If you are talking about were you would put adapters your case should of came with those and when you install an adpater you pop it out to expose the port. If Im not even in the ballpark give me more details.
