Fixing a bump on Tsunami case

[Olyros]

Hello, I have a Thermaltake Tsunami all aluminum case (the silver without the window) and the right (when facing the front of the case) side panel has developed a little bump besause of a fall.Do you know or have any ideas on how to make this flat again?
If I heat the spot with a heat gun, will I be able to flatten it through pressure?
I feel really frustrated when I see it ,so please help!
Thanks.

2 pieces of hard, flat plastic. Sit it on a hard surface and tap it out with a hammer. (Use the plastic pieces as a buffer to prevent scratching)

Got pics of the dent?

Well, I would post a picture but I don't have any camera.However the bump is pretty typical, it's its spot that troubles me: just at the end of the side panel, almost in the corner.

The same way you flatten a bump in most kinds of sheet metal.

You get a flat chunk of steel and hold it behind the bump, pressing it hard up against the area where the bump is, then you tap the bump down flat with a small hammer from the other side. The flat piece of steel keeps you from going too far with the hammer and keeps everything lined up.

If the area is curved, then you need to find a curved piece of steel to use as the backstop and keep the proper shape.

Behing the bump there is this thin line of metal coming out from top to bottom that is used to hook the panel back on the case and so no flat surface can be placed behind it .It looks like the panel is doomed...
