Actually, moving the wires and using the reset button for power is a common practice often recommended and IMO, is a great idea. With some motherboards, you can then go into the BIOS setup menu and change the function of that switch so quickly pressing and releasing it powers the computer on, or if already running, initiates a reset/reboot of the computer. And pressing and holding it down for 4 seconds forces a power off. In other words, you still have both Reset and Power functions, but now they are in one switch.
Note it is not always possible to actually move the switch - it depends on the case and how the switch is mounted. With some, the actual switches are mounted inside molded plastic pieces at the factory, with the Power mount and button being larger than the Reset. While the actual electrical switches are likely identical, you have to break the plastic mount to get them out. And once broken, you are hosed.
Other cases use plastic prongs to lock the button in place behind the front panel, but they can break easily when removing the old button. Then the new will not stay in place.
I've seen in other cases where the switches are held in place with bent metal tines. The problem there is you have to unbend those tines to get the bad switch out. Then bend them back again to hold the new switch firmly in place. The problem there is when you bend metal back and forth (even jus a couple of times - and they were already bent once during factory assembly), it loses tensile strength. This can result in the switch no longer being held firmly in place, and can pop loose.
So it typically is just best to get into the habit of using the Reset button from now on unless 100% certain the actual switches can be moved without breaking the mount.
