I just purchased this dual 800mhz G4 quicksilver mac with 1.5gb ram, original graphics card and an 80gb hard drive for $100. I think it's a great deal, even if I had to throw away the old DVD drive and put in the one from my previous mac. I searched macreviewzone but there's nothing that compares this desktop to another like the G4 digital audio systems. I am curious about performance comparisons with my older system, the 533mhz digital audio G4. Does anyone have any comparisons to that or a similar system? I am not noticing a huge difference, but there is some improvement with rendering changes in lightroom. Thanks!
