coffee damage for macbok

I have a Apple MacBook that my girlfriend spilled coffee on some weeks ago.

I took the Macbook to a service centre who offered to replace the battery and harddrive for 600$. In doing so they removed the back and the screws.

I thought that the repair price was too expensive and thought I would first see if I coulddry the things out and reassemble myself.

Looking at the back of the computer I do not know where the screws need to go and hoped someone had some dis-assembly instructions?

I have treid to use common sense, but have failed the logic test!

I have the new version of the white macbook.

Can anyone help??
