Behold. (And I've added it to the article, too.)
(I may need to obtain a few more power-boards, or PowerCubes, to replace the remaining monsters with; I'm thinking of trying thrift stores, as they might have some older and better-built units. And the UPSes at the office may well contain a few more of the devils; so I'll have to check those out too, even if it means sacrificing warranties…)
Update 2018-06-10: We're in luck, as I've tallied up my Mum's office and we'll only need to replace
two remaining El-Cheapo power strips.
(I've already succeeded in getting rid of all but one of the computer-murdering units, and that last one feeds just one UPS so we really don't even
need it.)
For that purpose, I can replace one of them with a somewhat-modified PowerCube (I've added a thermal fuse in series with its MOV, and taken out the rather-unreliable shutter mechanisms), and the other with the Arista SPB 1 (shown at the end of
my PowerCube review, for size comparison; it contains no TVS).
Information is far more fragile than the HDDs it's stored on. Being an afterthought is no excuse for a bad product.
