I did the same here too, about 15 pcee's hooked up to a linux box hooked
up to a cable modem.

One of the second hand computer stores here is selling machines for 1$/MHz
I used a P90 with 64M of ram, 3G IDE disk and 2 Dlink Tulip cards
(DE-530Ct) Total cost was approximately 600-700$cdn.

If your machines are slow and ISA go find a local used parts store and
pick up some used ISA ne-2k's for a few bucks each.

Definately! Depending on your building you might have to have it
professionally wired to clear any local firecodes...

I like to run squid for web proxying and use DHCP to configure the windows
machines. Squid saves bandwidth (we get a 49% by byte hitrate here) and
DHCP makes windows work quite nicely. (I have a setup for this too if
you are interested)
