Old topic for sure and discussed all over the web, but I've decided to ask here since the pics are very informative. I've seen where those 3 near the PS need to be replaced if leaking/bulging, and the clock cap for sure... but that is only 4. I've seen talk of 5 (including one of the responses here)... is it specific caps like the 4 plus another that are typically troublesome, or should I just pop mine open and take an inventory instead? It's almost at that 20 year old mark... :/
