That would be fine if they didn't need screens ;-)

12v gets eaten up by cable resistance over a long distance ( such as
round an office)
and so you would get far less reliabilty under load.

If the compuers , wiring and building where designed with this in mind it might
be possible to make it work but i would have thought the consultancy and bespoke
kit costs alone would dwarf the money saving for at least 10 years or so.

Tis a nice idea though .
