First of all - the computer is over 25 years old. So, don't expect much from it. :-)
 
From another hand, as a "fun project", to learn new things - it's perfect. At that time technologies were not that advanced, so, a lot of things were "repairable".
 
1. Don't replace components just because someone else replaced them - evaluate them first. First sign that electrolytic capacitor is (may be) having a problem - the top is not flat. If it shows sign of "burst" with leak, or even little bulging - it's a candidate for replacement.
 
2. Look for "discoloration" of any components (resistors, transistors, etc). Again, it could be as bad as a "burn mark" on the motherboard, or as little as "little bit brownish spot" on the component. Use a magnifying glass and good light source to examine the board.
 
3. Not sure, if you can find electric schematics for that old computer (especially with the fact that Apple do not publish their proprietary stuff), but that could be next step up, if visual inspection does not help.
 
...
 
99. Bad result is also result. Even if you unable to fix it (sometimes things just die beyond repair), you will get valuable experience.
 
Good luck,
