I use something like this: Removable Wide SCSI Drive Mounting Kit - Mounts 3.5" Wide SCSI Drive in a 5.25" Bay, with Module, Frame, and Cables, Beige



Mine is well over 10 years old though and does not have a SATA connector. I have this mounted in a computer, and I boot Knoppix from a thumb drive. I use the fdisk command and gparted for partitioning and formatting, and the shred command for overwriting.
