If they are front mounted, then they will link to a section on the motherboard.
I couldn't find a decent pic of what I meant, so here is an amazon link

You can see the long pins on the Male side of the cable there. On the MOBO they will be the same, my only caution is that they can bend easily, but they are hard as shit to actually break. If you do bend one, use a credit card to bend it back in line from as many angles as you can.
IDK if this makes sense
