I did this earlier today using capacitors from old motherboards. I'm glad I didn't wait longer to do it. Even so, I should have done it much earlier. You'll eventually find out why...
Original capacitors (all are 10mm except the +5VSB):
Replacement capacitors:
I also replaced the primary caps (Teapo LH 680uF 250V) with Chemi-con SMQ (same value and voltage). Best to be on the safe side.
I was originally keeping it on the list of spare PSUs to be (eventually) recapped. Only today did I discover that the repair was overdue.
I went to install the fixed PSU in my PC. I pulled another (unrepaired) unit out of my PC. I waited long enough for one of the +3.3V caps in that one to go from non-bulging to leaking. (In case you're wondering, the +5VSB caps in that one weren't bulging.)
The only symptom of that crap was a faint high-frequency whine.
Morals of the story:
Any comments???

Morals of the story:
- Even totally busted caps don't always show obvious symptoms.
- NEVER leave crap caps alone.
- Never, EVER use an HP-D3057F3H with the original caps.
