I don't see why you have assumed that one of the capacitors has leaked. The corrosion could have come from water or condensation onto the board.
I don't see any corrosion on the components.

It looks like there may have been capacitor leakage and some heatsinks will need to be replaced. I have posted pictures here: https://robs-old-computers.com/2017/10/23/corroded-h7826-power-supply/ So two questions: 1. Any suggestion on how to clean the board? Some of the corners are a bit inaccessible to reach with just a cotton bud and isopropyl. 2. Do those heat sinks have a particular name/spec that I can search for? Thanks Rob
