My idea: seriously consider buying a ~$300 notebook and use a USB NIC
for the 2nd port and USB serial convertors (I know you stated "not usb",
but you gave no reason for that - the advantages of using a notebook
may, or may not, out-weigh whatever reasons you have for the serial
ports not being USB).

Advantages: cheap, has built-in console, has built-in UPS, low-power
(relatively), easy to replace if/when needed, ample storage/RAM etc.
