e521 motherboard

I have a dell d521 desktop that was damaged by lightening. The powersupply is bad and the ethenet port damaged. I was am thinking of repairing it but I am not sure of all the damage since I can’t turn it on with a bad power supply. It has a BTX motherboard with an amd am2 processor. These boards are hard to find. Is there a way to test the board to see if any thing else is wrong?
