If you're going to insert/remove a USB device several times a day, a 6" extender cable will keep your motherboard jack from going defective. Less than a dollar apiece, too.
There are cheap extender cables for PS/2, audio, VGA, DVI, HDMI; I don't usually recommend them for RJ45 because you can compromise signal quality on gigabit connections, but unmanaged 5 port switches are cheap enough.
One rule of thumb: if the cost of the labor in replacing a component is half or more the cost of the component, see if you can insulate yourself from replacing that component. When pulling cables through buildings, the labor cost far outweighs the cable cost, so pull many spares at the same time.
