Most interesting, David. Thanks for this post and pic. I'll keep in mind.

You are referring to your "server". But what do you use as your "client"?

And just following on from the above, one can have a setup using a car 
battery, and kept up to charge via a charger, plus a bit more fiddly 
bits, to run your computer and therefore without the need for a PSU and 
which would not only give you a stable power supply but also be immune 
to power fluctuations or power failures (the latter in the short term of 
course).

There is an article on how to achieve this but I would need to go 
searching for it in my archives (seeing as how my friend, who has since 
deaded himself by having a heart-attack and now cannot provide the info, 
was using this process).
