Actually the "hard drive" ATA interface is ATA/66 or more properly ATA-5, which is a significant improvement over the ATA-3 interface in the PCI G4 and earlier machines. The "cdrom/ZIP" interface is ATA-3 and can also be used for a hard drive. Most modern drives run cool enough that they can live in the zip slot without a problem.
