Hey, I'm auctioning off my old G5 tower, since I now have a Mac Pro.

I started the auction at $1 with no reserve :-)
its got dual 1.8GHz G5s, 2 GB of RAM, two 80 GB hard drives in a 160 GB fast raid. The front firewire port is dead, so I installed a 4 port PCI firewire port. They all work great with no drivers needed. Also it has a firewire 800 port on the back. Working USB ports front and back. A video card that drives two monitors. It also has a built in 56k modem (haha who dials in these days, although I've found those 56K ports come back to life for sending faxes from the computer). Also Airport Extreme, 8X Super drive. Possibly more that I'm forgetting.
