Sorry to hear that, I hate when that happens.
Had some friends who were awakened one night thinking they were being attacked - a lone kitchen cabinet full of plates and glasses had fallen off the wall and crashed into and dented the stove while sending every plate and glass smashing to the floor.
Even if your components were completely damaged (looks like the majority may have survived), a used setup can probably be purchased for a couple hundred dollars. Bigger question is how is the car?
