A partial solution could be your spare desktop acting as a bridge(4) 
using two NICs, and sysutils/darkstat as the monitoring software.

If you can't or don't want to pass traffic back and forth through the 
spare desktop, try port mirroring (Cisco SPAN port/monitor session), 
"ifconfig em1 up monitor", and sysutils/darkstat.
