I had a bunch of 3000 power supplies recapped and they all failed. One even blacked the pin connector on the mother board. Make sure the caps are the highest quality, I have a feeling the person used junk caps, but maybe there is more to it than that.
Do yourself a huge favor and get a plan b to get a modern replacement. A long time ago someone in the interwebs was offering a service to mount guts into the original case, you want want to look into that, or just buy the adapter and work around the cosmetics.
