This post is not about bad caps as a whole but as the photos show its possible that a tiny cap or similar component could be blown. The burning on the motherboard is clear to see. The motherboard is an Intel OEM board from an Acer computer. I can think of 3 possible causes of the damage.
1/ As the computer was run for long periods with no side cover its possible that a metallic item was dropped on the board while connected to the mains
2/ One of the front USB ports are damged causing a possible short circuit
3/ The heatsink and fan unit was totally clogged with dirt causing overheating.
My guess is the USB port. You will also notice that the damage is very close to the front USB port headers. The model of the motherboard is an Intel D915GAG (SKT 775)
