I'm pretty sure the "what's this" part in the bottom right corner of the 2nd picture is the hard drive. That should be salvageable. I'm guessing that your pc is a prebuilt from hp or some other company. From what I know, I believe that your motherboard got fried. [strike]You probably don't want to keep the power supply, as if the case is indeed that your motherboard got fried, it means that your power supply wasn't good/ powerful enough (need confirmation for that).[/strike] You can keep the dvd drive, but it isn't worth much. You can buy a new one for $15, and a used one for even less. You can keep the case and case fans. I think you should be able to take off and keep your processor. The motherboards probably gone. You can keep your ram. You can also keep the network/wifi card/
[strike]All this is assuming that your motherboard is fried, but I may be wrong. [/strike]I'm not fully sure if my info is 100% correct, so I'll need some confirmation from someone more experienced
