Since there is almost certainly nothing on this board using 63 volts
it might be argued that the capacitors were jsut defective and another
63 volt one could be used in it's place. If someone had a voltmeter
you could pretty easily (granted, with a PCI extender card which
normal users probably don't have) look at the voltage actually on the
cap and choose a value higher than that by some margin.
