This one was my second Power Macintosh (the first was a 7200/90). Heavily upgraded in the years. First with a Sonnet Crescendo 233/512, then a XLR8 Mac Carrier with PPC G3 at 350 Mhz, followed by a PPC G4 at 450 MHz and finally by this Sonnet Crescendo PowerPC G4 7455 at 1 GHz. An Acard IDE PCI, a 3dfx 3 2000 and a Lucent USB PCI complete the heavy upgrade. It is rock solid and the king of the basement collection
