Aren't concerned about my guestamatted through-put because your not on

A cheap, throw away pentium and a couple of nics will do the same job

a
floppy if you wish, add a hdd and it will make a good appletalk file

Cheers all. ;)
Worth considering. I bought an independent "nat" router that runs on 9
watts, but may want greater security and configurability in the future.
100 watts, run all day long, costs about $57 a year (based on 6.5 
cents/KWH,
may be higher in your region). In 5 years that's about $285, just for 
the
POWER. If the unit should take 200 wats, the power costs double, over 
$500.
Unless one really needs the configurability or extra computation 
capability,
this may not be a cost effective solution over years of use.

That's why I was interested in a unit that would run for 30 Wats or 
less.
There are reasons to use a program-onself router/firewall, but saving 
money
is not one of them. A low power relatively modern "green" computer 
could
save its own cost over a few years, so using these older machines is 
not
necessarily cost effective in continuous operation.

That is why I was asking if anyone has measured the power usages of 
these
machines, the documentation I found was inconsistent and also doesn't 
really
represent the actual in-use power usage. If anybody has power use 
figures
that include any "green" PC's, as compared to the Quadras/ and Power 
Mac's,
that would be an interesting comparison.

With a disk that shuts down, and sufficient RAM that it does not need 
to
page, the computer could be running in low power mode most of the time 
and
use little power. There is of course no need for power hungry 
peripherals,
except for the nic cards. That is a reason the floppy boot would also 
be
useful -- it can't page, wasting power on a hard disk.

Thanks

Thanks for the replies, I guess it's just good for old games.  I have a 
DSL router already, so I will just stick with that.
