You're right that the disk drive cabinet would have been at least 250 pounds. Those multi-platter pack drives had huge transformers for the power supply and a linear motor that was 100 pounds, all by itself. And a fairly large support structure in the cabinet to support all that. So they were pretty meaty boxes.
Back in the day, I considered experimenting with using one of the linear motors from a Data General Zebra disk drive as a big subwoofer. But at 100 pounds, I just never "got around to it."
