The capacitors on the main board are notorious for leaking, and I narrowly avoided permanent damage to mine when I recapped it. Might as well toss on a new belt as well if you are going that far.
Agreed, all these issues are only a matter of time. The first time I worked on my model 1, I only replaced the fuse. A few months later the caps went out. You can tell this when you turn it on and only the background screen loads, no menu options or Sega logo. Do it all at once and save yourself some time and headache.
