I bought this iMac in Mid-2000 to run AutoCAD on it. I never could get it to run AutoCAD. By the time I gave up on that idea, it was too late to return it. I tried to use the Garage Band on it and I gave up on that as well. I also changed the hard drive on it once to put a 500 Gig on it to divide 250 for Mac and 250 for Windows. Now the buffer is the only thing I see. Therefore, this is good for people who know Apple and can use parts for it.
