Hi there Sarabian and everybody,

Thanks for your help. I think it's probably best for me to purchase the new operating system-- I have purchased extra RAM, too, to install.

So, my plan is to install the RAM, install the new hard drive, and then install the new operating system.

One last question-- maybe I overlooked it someplace, but I couldn't see the system requirements anywhere for Leopard. Any idea where to look for them, before I buy it?

Thanks,
