Recapping a 90411 from a Wizard of Wor and I found that the 20,000uF @ C2 had the traces scraped back from the pad a little and the legs were soldered to both pad and the exposed trace. Didn't think to get a pic before I removed the cap, but this is what I found once I got rid of the old solder and flux.

The cap has a date stamp of 8047, so I assume these are original (the other caps on the board are all similarly old). Curious why someone thought this necessary and if it was something they might have done during original manufacturing.
 
Probably the legs were a little bit longer or been soldered in that way for extra stability.
It might be possible that capacitor was replaced by somebody with one "original" - from another board.
Doesn`t look like a factory job - unless you scratched the board like that during cleaning.
Anyway, nothing wrong there - except the visual "disturbance"

Noticed that -maybe- you have a pair of extra holes - as far as i remember should be only 4 holes for support, but it might be different version.

You're probably right, someone swapped it from a spare board or whatever they had lying about and thought they needed some extra surface to solder to. With new caps, the power supply is working just fine so it's just an oddity to look past I guess.

As for the extra holes, my board is a C000 revision which could explain the variance. I used the extra holes to hold the new cap in place since it's so much smaller than the original... maybe the rev C designer realized caps wouldn't always be gigantic and added them.
