I second all Fred said. I have a 200MHz Pentium w/96MB running IPCop
(1.11 now) and it just hums (eliminating fans would eliminate the "hums"
too!  :)

But, I have also installed it (for test/backup) on my wife's discarded
Aptiva w/ a real 486 and very little memory (I don't recall how much,
whatever came from the factory... 32MB, 64MB, 128MB?).

Also on an AMD 486 clone (x586?) 100MHz with 36MB of memory.

Only differences observed seem related to half/full duplex nature of the
NICs and raw speed. With my cable being in the "boonies" and a stock
Toshiba cable model, good sites get me 600-700 kChars/sec on the
Pentium, appx. 530K/sec on the AMD and 460K/sec on the Aptiva.

With that in hand, Aleksandr's staple, $20 machinces, should fit in your
scenario very nicely. Like him, I have a bunch  of those (even some $10
ones - 386SX comes to mind). Find justification for their continued
existence seems to be my biggest problem! :P
