    I have an iMac (the version before any black was introduced) running OS X 10.4 (if 10.5 would help, upgrading would be an option) and I would like to connect it to two different networks - one for internet and one for file sharing and printing.

    Both have a modem connected, but I want to only want to use one for internet.

    The wireless one is the one I want to use just for file sharing and printing, the wired one is the one I want to use for internet access.

    Is this possible? If so, how?

    Yes. Either use static IP addressing on your interfaces or have two different DHCP sources, one for each network. Make sure the default gateway is assigned on the Internet interface and you're away. The Mac will find everything using its own routing tables.
