iMac G3 Stuck Power Button

So I bought a iMac G3 on eBay. It is a PowerMac 2,2 if you need that information. A few months later, the power button is stuck in. So I have to keep hitting the power button to get it to turn on. And if I shake the computer, it might turn off. Any solutions on how to get that power button unstuck. The computer probably wasn't handle the best as I see some chipped pieces through the case and the door for the RAM has tape on it since there is nothing to hold the bottom in.
