I replaced a modern retail firewall/router with a 500 Mhz Celeron with 
512K RAM  (Intel 810e motherboard) and a PCI dual port ethernet card of 
because the 'modern' POS turnkey couldn't handle 100 mbits/second 
through the WAN interface. The 500Mhz celeron with CentOS5 handled that 
plus DNS and DHCP without ever cracking 1% CPU usage.
