I got one nic on one single-core non-PAE i586 CPU (GEODE LX800) that
roars at 800MHz with 1/4GB ram. I got 1 hard drive with DMA, the
other "drive" is a CF socket accessed by PIO.
Look up the ETX boards, and consider those with 4 amps max total
current.
They're used all over the world for process control and
special-situation comms systems.
It's headless, access is by ssh; it *must* go from power-on to full
operation in 90 seconds, it *should* get there in 30. That includes BIOS
startup. Once installed, it does NOT change hardware configuration
exception hard-drive-swap for application version upgrade every 2-3
years.
