I just got a dual 2.0Ghz PowerMac G5 and maxed it out at 8GB of RAM. I really love this machine; I even put LED lighting in it xD. For a little while I was using a PowerMac G4 MDD dual 1.25Ghz alongside the other main computer I use. It's sitting in my collection as of now, but still a great machine. I have every PowerMac G__ from the 1997 PowerMac G3 desktop and mini tower to the PowerMac G5. I think the PowerMac G3 Blue&White looks the best out of all of them. I really wish I could get a quad-core G5. The place I bought this dual-core from had some, but by the time I had visited their store, they had all been sold. I gotta get some SSDs later on when they go down in price. I badly need one in my 2009 MacBook Pro, which is the only Intel Mac I have, and of the very few Intel Macs I cherish. It would be cool to stick one in the G5 as well. As for my other PowerMacs, I got the beige ones for free, talked the Blue&White model from $100 down to $5, the PowerMac G4 (graphite) for free, the Cube(s) for free, and the Quicksilver, MDD, and G5 purchased. It was kind of cool to start using the MDD is a main-ish computer. Prior to then, I hadn't really used a "pro" powerhouse Apple computer, just all-in-ones or laptops.
