You might want to consider separating the firewall from everything else. What you want from a firewall machine can be (and probably is) very different than what you want from a "server". > > A) Sun Fire V100 UltraSPARC IIi 650 Mhz - 2x160Gb Hd - 2Gb RAM - CDROM -> > > US$ 350 > > > > B) Apple Power PC G4 733 Mhz - 768 Gb RAM - 38Gb HD -> US$ 320,00 > > > > C) Atlhon 64 X2 +5200, 2 GB RAM, 160Gb HD -> US$ 320,00 Assuming that each of these is enough for your intended server, I would go for the Athlon, because i386/amd64 hardware is ubiquitous and laughably cheap, so if something breaks, you will find a replacement for peanuts. No exactly so with Sun or Apple hardware. That said, $320 seems to much to me.
