I see a bit of green gunk at the point where the leads exist the body of the axials -- always a sign of leakage. Furthermore, I was brushing dust on the board away with a small paintbrush when I noticed that I was starting to paint with a clear liquid. But I did not spot any eaten traces.

Assuming the 040200 Sad Mac Code is RAM related, does that code point us to a specific chip on the board?
