There are usually a couple of small screws on either side of the switch. You'll have to take the side cover(s) and front cover off. You will need to trace the wires from the switch and notice where they are plugged into the motherboard. There is most of the time a triangle on the plug that connects to the motherboard, that triangle needs to line up with pin one of the "jack" on the motherboard. On some motherboards that matters, on others it doesn't. It isn't that hard, and there's no danger. The biggest problem is some systems are really cramped, and you have to be able to trace the wires.
It is to open the power-switch at zero current to minimize the looses during switching.
