I'm sorry, but that's not possible. Snow Leopard requires an Intel Mac. Yours is a PPC Mac. 10.5.8 is as far as you can take OS X on it. To run Snow Leopard or later requires that you buy an Intel Mac.
OS X is not available as a freebie. New major versions such as Snow Leopard, Lion, or Mountain Lion must be purchased from Apple.
