I forgot to mention how I got the eject button in and permanent.

First I had to use a 5/16" drill bit to make the hole smooth. I did not use a drill, I just slowly rotated the bit by hand so that I could control it the best. I started with a very small one and worked my way up.

Next, The button I had is from my IBM Aptiva case. It was a little long so I measured how long it needed to be and filed it down accordingly.

Then I got a safety pin and heated it up with a candle hot enough to poke through the end of the button (The end that will be inside the Mac.) I then cut off the part of the pin I did not need. Here's a drawing of how it turned out (and how it is mounted)
