Right. You'll *have* to get at least a socket-7 motherboard with a K6
processor and DIMM RAM sockets and PCI bus, if only because getting
old-school SIMMs is hard these days. And getting a distro with install
kernels (much less stock kernels) for less than a 586 is getting hard,
unless you opt for something like Slackware or Linux From Scratch. In
practice any still working minimually i686 system with a reasonable
amount of RAM (for just a DNS server, 256meg RAM and a 20-40 GIG IDE
disk, would probably even be enough to install, say, CentOS). I
recently installed CentOS 5.2 on a old Dell box (PII or PIII vintage)
with an 18gig disk. No X11. Just DNS, DHCPD, PPPD, Samba, CUPS, and
little else. This little box is just being used as a dialup 'router'.
It is jacked into a wireless 'router', but the wireless router is just
being used as an accesspoint and Ethernet switch (this is a home setup
-- broadband is not presently available, only dialup internet).
