Then where are you going to get system power?
A non-wall-wart external supply, presumably. While I'm not quite as
vociferous about it as Ben, I don't like wall-warts either. I'd much
rather use a power-brick style supply (ie, a device with a - preferably
detachable - mains cord, and another cord to the powered device).
I'm not terribly fond of them myself, but I don't really mind some of the
better made switch-mode wall-warts, and some of them are even assembled
with screws. That said, I have had to replace quite a few faulty
electrolytic capacitors in a number of these devices...
Poorly made power inefficient (20-60%) linear transformer type wall-warts
on the other hand annoy me to no end and I'll use a switch-mode type
wall-wart (80%+) in place of a linear transformer type whenever possible.
When you have dozens upon dozens of them in use, the heat generated from
the wasted power becomes noticeable.
