I'm looking for a desktop computer for home use, I've been looking at used iMacs on eBay, and the price difference between the white duo core iMacs and the newer Aluminum ones is quite significant. The main uses for me, are Internet, Music, Films. I'd like at least 250gb HDD. And preferably Leopard. What advice can you give me? What is the best option for me? This is my first post here, I've been viewing these boards for a while, and found it to be a valuable resource in my switching to mac.
