It's about 8" long, x 7" wide x
3" tall, and has a dual DB25 connector at the
rear, along with power and a rotary device selector switch. The box is
early-Mac-colored. I've probed underneath the rubber pads on the bottom of the
box and find no suggestion that there might be screws there, though I could be
wrong if they're really short. The way the plastic shell latches together is
relaly typical of early MAC stuff, though it might not really be MAC, but maybe
Apple-II-something.
I have one of about those dimensions that has four identical rubber
buttons on both top and bottom. The buttons are perhaps 7/8" diameter
and show on the side of the box for about that same dimension. A bit of
judicious work with a small screwdriver will jack mine straight up.
That done, exposes screws on the bottom side, and unused provisions for
same on top. Mine, however, has dual 50-ribbon connectors on it -
definitely SCSI and Apple also.

The interface is pretty clearly SCSI, else it
wouldn't be able to identify
itself, though it doesn't spin the drive up.

There were a variety of those external drive boxes, Dick. Some snap
together while others have screws hidden under feet, or ??? Can you
describe it?
