Hi Jim
I think upgrading to OS 10.5 is a big no no. Leopard is very RAM hungry. I have a 333MHz iMac running OS 10.3, it is a bit slow as I do not have enough RAM.
From the details you enclosed it looks like someone has put a larger hard drive in.
If you look at the descriptions found here http://www.mactracker.ca
you should find your machine listed but if you do upgrade I would definitely up the RAM to its maximum !GB
