what a hefty little number this is, super fast and dead easy to use and upgrade.
it comes standard with 2 USB ports and 2 firewire ports, a 16mb rage graphics card. it simply tears through anything like it wasn't there!, i've got a blue and white G3 (400mhz) tower at home which is more than a match for a 600mhz PCc, and it simply pails in comparison with the G4 400mhz i've been using at work lately , they are, as apple claims, twice as fast as the equivalent Mhz'd G3...i cant wait to get hold of the G4 500mhz. the machines are beautifully designed - something to behold rather than the tradition dirty grey box... the small handle at the side topens the side panel up for access to the hart of the machine, no screws.. no nothing.. apple have taken their plug in and play attitude through the software down to the hardware!
