I Dropped my Macbook Pro and dented the bottom right corner of the bottom pan.

The dent caused the DVD slot trim to bulge out a little too. The mac works fine except for the Dent and the bent trim. The plastic seems to be okay too. It is more cosmetic than anything, but I would like to replace the bottom pan/cover.
Can I just unscrew the bottom cover and replace or is everything inside mounted to the bottom pan? I don't want to have to pull apart the guts to replace the pan because I know it will never run right again if I do... Suggestions?
