Attached Link: I/O Magic USB 2.0 5.25" Hard Drive Enclosure Kit

If the computer in question has a USB connection, you can get what's called a USB kit that will hold the hard drive. I've got one and love it. I intend on using it to transport files and stuff back and forth from work so that I can work on stuff in both places and not clutter up my work computer.
