No, go read my post. Everything goes within the box with the exception of the power LED...which is just to the left of the box between the box and the first yellow USB connector.
A speaker connection would be a 4 pin black connector just like all of the others that you have. It would say speaker or SPKR on it. Since you don't have one...don't worry about it. You just won't use any of the 4 pins that are showing on the upper right side of that block.
