No, I've changed all smaller electrolytics, the big brown 6800?F and the
big filter caps after the rectifiers remained untouched.
The bigger caps aren't loaded that much in relation to ther volumina
with pulsed currents as the smaller ones and the se works better on big ones.
The ability to dissipiate heat is also better for big capacitors and that's
the cause that they are still wet internally and therefore still working.

This Capacitor was bad in my PSU too and I've changed it.
In the light of what you say below, do you mean you only changed this one,
or did you change all of the ones on the logic board? Does that include the
really big ones too?
