I don't think there's anything particularly critical about it. I'd use
one of those SMPSU-rated capacitors (sold for TV repairs, etc). I'd
probably fit a 105C one as well, to save having to do the job very often.
Let's see...
SMPSU, as in Switching Mode Power Supply Unit?
105C as in temperature rating?
In the process of looking up those, I found an interesting reference:

The value doesn't seem to be that critical. 100uF
should be fine if
that's all you can get.
Hee hee. That is exactly what the temporarily replacement is. (But it
certainly isn't rated for use in switching supplies, and certainly not
marked as 105C).
(As an aside, I am still attmpting to work out why HP
fitted both 5400uF
and 6000uF smoothing caps on the same board (the former for the -ve
supply, the latter for the +ve supply). There was ample space to use
6000uF caps for both.)

If they expected to make a lot of them, every penny counts. Kind of like
saving weight ounce by ounce on an airplane that weighs tons. Or, maybe
their supplier couldn't get enough of one or the other. Or maybe they both
started out 5400uF, then they found that one of the supplies needed 6000uF
for some reason, but they only made the change once. Or, more likely, it
shall forever be a mystery.
