sorry the caps are not always bloated, quite often they leak the
acids out(dry out effect) and instead having the eg: 100uf the value
is down to 10uf, an electronic guy (like me) has to take the board
out & remove them to check the values it is similar to cd/dvd player,
and also a video camera guy confirms that he has to do the same job
when repairing a camera

It does sound rammy.
However, if you are game AND you have the iMac that is easy to
open, a few screws has the back off and a quick look will tell you
if the capacitors are bloated, they should look cylindrical with a
flat clean and shiny top surface.
So far I have not seen bloating in the caps that have a 'K' cut in
the top as opposed to an "X".

Not sure if Apple is still happily repairing these iMacs with
bloated caps.
Good luck
