I have the rev. 6 board, and it is the capacitor beside the battery in position c912
You don't say what help you need. Do you need to replace this capacitor? If yes, all the information you need is written on the side of the capacitor itself. You need to source a replacement through-hole electrolytic capacitor with the same capacitance (470uF?) and the same voltage rating. You can go higher with the voltage rating but don't go lower. Also, if you're anything like me, you will want the same physical size capacitor to make the repair as inconspicuous as possible - although a battery leakage may have put pay to that idea, depending on the extent of it. Anyway, if matching the size is important to you then measure the diameter and height and add this to your search filter when selecting a replacement.
Check
here. You will see I already added some relevant filters. There are diameter and height filters if you want those, and you need to set the correct voltage rating filter.
I also removed the cpu socket, so any help finding a source for those would help also.
This is potentially more difficult. You're looking for a through-hole PCB edge connector, but the problem is finding one with 86 pins. I had a (quick) look but couldn't find one at my usual sources. Perhaps someone else will reply with a good source for these. If not it will be easier for you to salvage the old one if it's still possible, otherwise perhaps you can source a larger edge connector and carefully cut it down.
and the strip capacitors
What strip capacitors? You will need to be more specific for me to help you here.
Also, please consider posting a high resolution photo of the damaged area of the motherboard. It will be interesting to see the extent of the damage and there may be more advice that can be offered with respect to it.
