DA 533 single that I bought a little before the time the Intel Macs were released. I thought it was finally time to try a Mac other than the woefully outdated 68k and PPC 601 machines I had been collecting. It was formerly a school lease that was being traded in so naturally it was a bare minimum configuration with only 256mb, 20gb and Rage 128 graphics. I bumped it to 768 mb and installed a flashed Radeon 9700 and it runs Tiger fine. Something happened to it recently, though, because the built in ethernet port stopped working the same night we had a thunderstorm. I think a surge fried it. I don't have a wi fi adapter or a separate ethernet card for it so it's been offline ever since. Still, cool machine with lots of upgrade possibilities but for the cost of upgrades a G5 machine would be in reach so it's probably not worth it.
