I bought an E-SATA base for $25.00 I think and a couple of 500GB SATA HD. I then bought an E-SATA card. All I have to do is plug one of the 500GB HD in the external bay. It pops up as an normal drive, let Acronis do its thing then unplug the drive and shelf it. I do that once a week, takes about 30-40min per machine and runs in the background and it's automated. Just have to plug the drive in the bay and power on, but I usually get an email from Acronis Scheduler telling me I forgot to backup so I have a reminder and I do it on the spot
