Gary your hard drive should be salvageable. I know a bit about computers. Did you shut it off or did you run it till it shorted out?
Gary if you send the hard drive to me. We have the technology here that the Feds use to recover hard drives of Pedos who have smashed them or even burned them. Message me if you are interested.
Better yet take a hammer to it theres a nifty little magnet in side great for picking up nails . One of the only usfull things to ever come out of a puter
