I purchased 4 of the IBM power supplies. Plan to use the Offset Terminal Lugs miaviator discovered and these barrel plugs with 18 AWG wiring:

Any tips on where to buy the wiring? Home Depot did not have any 18 AWG and Radio Shack I'm sure is over priced.
i used 18-2 door bell with 50 feet was $7 and that for both strands. i hook up 20 units and still had a bunch left. been running on it over a week with no problems
Not it is sloid core wire not stranded so the wires are stiff and a little hard to manage.
