They're about the only company I know of that

Now that I think about it, I'm surprised that I don't yet have a bad
back thanks to my IBM gear.
Of course, having 100kg of ballast in the bottom does give you the
rather handy feature of making the rack not tip over and kill you when
you pull a machine at the top...
I've seen plenty of DEC cabinets with a couple hundred pounds of
counterweight in the bottom _plus_ anti-tip feet. Fortunately, I've
never had the pleasure of one tipping over on me, so I can understand
why they do it.
The closest I've personally experienced was trying to extract an 11/750
out of a minivan solo. I managed not to crush me or crunch the CPU, but
it was tough.
I _really_ don't want an SA482 cab falling on top of me.
