an old 2509/11 and a soekris 4801 draw under 0.2A here (nominally 240v, more like 230 in reality). 1U for the cisco, the soekris will squeeze in anywhere, and it's an easy 1-man job to rack (and easy to carry in a rucksack which makes things easier if you're, say, travelling by train) multiple low-density puc(4) you'd need a bigger PC which I bet would draw more power than this. if you can get multiport puc(4) (Wim has them) you can get 8 ports out of a soekris which is probably about the most power-efficient way. USB - the number of boxes I've had to disable USB on to stabilise, this would not usually be my first choice. ymmv, as they say (-:
