The server PSUs that I like are the HP 1,500w common slot PSU (yellow label on top, takes 220v) and the DPS-2000BB (220v). I use them with breakout boards, not wires. You can strap or screw in a heatsink on the HP 1500w units and that will help keep them cool and the fan noise to a minimum. Easy to fit one of these into a 4U Rosewill case (HP PSU). Can't speak to the particular one on Ebay.
