Specs:

1.07ghz G4, 768mb RAM, last version of tiger, 80gb HD

1. I have a 80gb HD of which 7 gb are free. I'm wondering, what are some common places where tiger stores junk? (temp files etc)

2. How can I speed OS X up?

3. Would Leopard run as fast as tiger or faster?

4. Can I software overclock things?

5. What are some of your own speed tips?

Thanks a bunch!!
