i thorough i might as well post the results of my nearly completed g4 ftp server, i have added a 40gb hdd in the zip bay, a usb 2 card (i have 2 usb drives for the server), a usb sata controller (plugged into the internal port on the usb card), and a firewire ata controller (pluged into the internal port on the mac's logic board) i still have one more sata hdd that needs to be plugged in
you can see the horrible old pc server i pulled all the drives from in the corner
