replacing metal chassis after bad fall

I did it! I somehow managed to knock the MBP off my desk and onto the floor. It still works (I am writing with it now) but the chassis is badly damaged and I fear I could not insert a disc into the drive. Dust will get in, it may fall apart, etc etc. Do you know if the chassis is available as a spare? I am also asking the local dealer but there may be tips or suggestions?

One very very stupid user....
