I had a craptastic Acer that was given to me because it had a dead PSU. The only spare PSU I had used a different type of switch (seems like one was a 4 conductor, and one was 2, or a rocker switch versus a push button, or something like that), and the original power switch was a PITA to get to and swap out. So, since it had this really funky drive bay door, I mounted a second power switch in one of the unused 5.25" drive bays behind the door. Don't get the wrong impression and think I was stylish about it, and mounted it to a drive bay cover or something. Nope - pulled the cover and mounted it to the drive cage - didn't even keep the nice looking switch bezel. It was truly ghetto, and I wasn't sad to see it go.
