Picture of logic board is attached.
If you look close enough you'll see some streaks of white. I cleaned the board with both an electronic cleaner and rubbing alcohol, but the white marks remained. I believe they are corrosion (aluminum generates white corrosion). The internal RF shielding has spots of rust on it indicating that this Mac was once stored in a damp location.
There was no obvious leakage from the caps even before the cleaning (I recapped an SE 30 with significant leakage so I have a pretty good idea what it looks like). I could still be wrong, but this board looked MUCH better than my SE 30. Regardless, now that I (finally) pulled the ethernet board and discovered that it is at least linked to the problem, I think the next best thing to do is complete the recap. Regaining ethernet connectivity is essential to me since I use this Mac as the bridge between my old SE 30 (no ethernet) and the rest of my ethernet-networked computers.
Thoughts??
