You obviously let at least one machine talk to the outside world, after
all, how else are you reading and responding to this mailing list? :-) 
Yes, your LX does count as a machine, even if it's only running at
40Mhz.  :-D

I find a well secured openbsd box to be a nice secure firewall,
NAT/router.  I route my web traffic through a squid, that way I can
catch any possible rogue applications trying to talk to outside machines
over http, ftp, or smpt.  Local firewalls on all the boxes help too. 
Esp. on windows where you get pop ups letting you know what's trying to
talk to the outside world.

Yup, for every watt of CPU power, you need another watt (or is it more?)
to cool it.  RAM is cheap these days, ~$100=1GB.  So don't fret over the
memory.   There are machines I rarely power on at home for the same
reason.  They're too expensive to run, so I only power them when I need to.
