Adding or upgrading hard drives is equally simple: Just pull one of four trays from the computer, change or add the drive to the tray and slide it back inside. There are no cables to plug in.

The difference in price — and that it was in Apple's favor — was so surprising that I contacted Dell to confirm that I had not made a mistake in configuring its workstation.
