This cabinet had been in my shop for something like four years and its

Kind of amazing, **** happens when you expect it the least.

Well, that is a little unusual, as it had a steel back, not the typical 4
verticals with just a couple cross braces. I've had a few of those either
fail completely, or start to show signs of twisting, and I readjusted the
cross braces to resist the twist. Your cabinet clearly twisted also as the
first part of the collapse.

Yes, i saw how it twisted a second before failing.

I would never have thought that it could be possible.
I’d bet on a busted spot weld or a missing fastener or two. With a
rectangular back panel, all four corners must have bolts, or a twist is
likely.

I have always fastened (at the top) tall bookcases to the wall. I
guess cabinets should be fastened as well. They tend to be overloaded
by default.
