Think inside the box? (sorry. bad joke, I know.) 

If you look inside the box, do you find, among the controller cards
plugged into the bus, an ATA/IDE controller card?

Another thought that comes to mind is the USB<->ATA converters.

From here, with the limited information you've provided, I'm guessing
you can, if you have the cables and the spare power connectors.
