Failures/Capacitor Plague
Nichicon HM and HN capacitors from around 2000-2010 are known to fail. These capacitors fail due to the special Ultra Low ESR electrolyte that did not contain the necessary preservatives.

Nichicon PL capacitors are known to leak electrolytic fluid from the bottom, corroding the capacitor leads and the circuit board.
