Wow, that one is a mess... With that level of damage I would say just part it and see how many games can be fixed from what you salvage.
I hate parting a game but this one is too far gone to justify the labor to fix. And you will never get the smell out of it...
If you want to dispose of the cabinet I can take it to the bonfire later this month...
My Atari Video Pinball control panel was totally packed with a mouse nest and enough mouse droppings to fill my bucket vac... The smell was so bad I nearly lost my lunch a few times trying to clean up the mess. Good thing I have a spare control panel assembly from a water damaged cabinet that I can swap over... The rest of the game was fairly clean and did not have any wire damage...
