Hi, Does it worth buying Second Hand PowerMac G5 (2004) 2.0GHz, 1GHz FSB, Nvidia GeForce 5200? Snow Leopard is not supported, will Leopard works fine? Where do I live, that doesn't sell cheap, even second hand, but I got a good deal on that. Will it worth dumping my Macbook (2006) for that PowerMac? Thanks in advanced.
