I just love the design of these machines: the graphite color; the big Apple-logo on the sides; the handles on the top and last but not least: the easy way to open the hood.
FYI: this particular PowerPC is app. 10 years old, has dual G4-processors at 450MHz, 896MB RAM and two hard disks: 30GB for Mac OS X 10.4 Tiger Server and 80GB for data-storage. Maybe it ‘ll end up replacing the old PC-hardware that is powering this site, giving it a fresh install of FreeBSD during the summer holiday. ;-)
