Does anyone have a theory as to why all the capacitors

Cost cutting. That's my theory. Apple's market got tough around the
turn of the early 90s with PCs getting 'better' in the workplace and
Commodore's Amiga starting to make inroads on Apple's home and pro
markets. Apple set out to revamp the range and cut costs. So instead
of using the best components they used the cheapest ones. In the
case of the caps these were cheap electrolytic cans that were rated
as close to the required spec as was possible, allowing little room
for error or aging. As a result the machines worked great for the
first 8-12 years (remember just how old these machines are before
you criticise the construction!!) which was way longer than they
were supposed to last anyway, then after that the caps gave out.
FWIW Amiga users suffer similar problems with some of their desktop
models of the same age. We are not alone :o)
I would imagine pcs are the same way but who's going to notice
electrolyte leaking inside a landfill.
