It's done for. Even if you ever manage to dry it out completely and get it to run it won't for long because of oxidation and corrosion of the metal and electronic parts.
My advice is to take the storage drive out of it and use a SATA to USB adapter cable to either a new Mac + Migration Assistant, or a Windows PC with MacDrive installed to get at your files.
My computer is not working, is my personal data lost?
If you have a backup of your data already, then no need, just toss the machine into the trash, take it apart to look at the pretty parts or take it to Apple for recycling.
If your having trouble keeping a computer in safe physical conditions, your likely better off on a inexpensive Windows PC instead, this way you just buy another one.
I have several other Linux netbooks just for that purpose, designed to be used and abused if the situation calls for it.
