IBM, too, maybe...
There's an old story - almost apocryphal, I'm sure - about IBM's 3330 disk drives.
A full 'bank' of drives came as four cabinets of 2 disk 'drawers' that were mounted vertically, plus a control unit on the end (pic here: https://www.computerhistory.org/storageengine/track-following-servo-quadruples-hdd-density/ )
The disks themselves were 'exchangeable' - any single volume could be swapped for another by hitting the 'stop' button for the relevant drawer, waiting for the disk to spin down, opening the drawer, taking out ('dismounting') the disk that was there and putting a different one in, then firing that particular drive up again to make the new volume available to the system (and, yes, you could do that while the 'old' disk was actually in use - with predictable results!)
They story goes that while it was possible to open all four top drawers at the same time, it was inadvisable to do so since the entire 'bank' would topple forward (those 3330 disks were heavy.)
An extension to the story says that this problem was fixed by a special IBM part that could be attached - two extendable legs that attached to the front of the bank to provide extra physical stability.
