Quoted from fixintoplay:

Awesome, thanks! I did notice on the reverse (solder) side of the CPU, there are (-) symbols etched on one side of each of the 8 solder holes for that row of caps, so I was being cautious.
I do have another question about the C60 electrolytic axial which I am also replacing, but I have a radial of the same specs. Would that be an OK substitute, and does the "0" gray band indicate the pos+ pin? Thanks again!
[quoted image]

The grey band with the "0" is actually a negative sign. So that leg is the negative and the other leg (which should be slightly longer) is positive.

Quoted from fixintoplay:

Thanks for the responses! And you're right, one of the legs (the positive) is in fact slightly longer. I've got to figure out a way to remember that critical fact. So, generally speaking, axials and radials with identical specs are interchangeable as long as there is space available?

correct - and note that some board locations (like the larger filter caps) have through hole locations for either an axial or radial cap. If bending a leg from a radial cap back along the axis I would use some heat shrink (or maybe you need to add some extension wire).
