Hi, A buddy of mine's Mom just upgraded to a new iMac. I had helped him put a new DVD burner in her G4 a few month's ago. I told him if she ever wanted to sell it to let me know. I always thought the G4's had an incredible design and would be cool to have. I offered $200, but she wouldn't take more than $75. . Anyway, It had 10.3.9 on it, so I updated it to leopard. I'm pretty surprised it runs so well. It's nearly six years old! I don't think many 6 year old PCs are running Vista. lol The only thing I might do is add a bluetooth usb adapter to run my wireless keyboard. I have it next to my couch so I can surf while I watch TV. Works great! Specs: 17" 1.25 GHz G4 1.25 GB Ram Airport Extreme New Pioneer DVD-RW DVR-116D (The one I helped him install) Apple "Pro" Speakers (The round clear ones) Lots of fun. R.J.
