I have a bunch of the Dell 520's or 620's.. something like that model number at my work... Had to recap almost all of them.. They were during the time of the bad cap run!!!! They looked like volcano's too.. I have always noticed even in the iMac all in ones it's the Rubycon caps that burst...

Well the caps weren't "bad" in the traditional sense as in a manufacturing/physical defect. They were actually based on a stolen and incomplete electrolyte formula that was obtained via industrial espionage, which backfired since it was flawed. The companies that used the stolen formula knowingly, or unknowingly in a few cases, made caps that would blow after a short time.
