That power cost difference must be per machine? (Unless I'm just not thinking clearly now.) Consider:

For 20 systems, and a power difference per system of roughly 80 watts, that's 1600 W total. If they run continuously (8760 hours a year) that's 1.6 kW x 8760 hours = 14,000 kWh. At $0.10 per kWh (varies with location), that's $1400/yr.
