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.
DO you use a passive heatsink or one with a fan? I presume you just dab some thermal paste on and zip tie it to the exterior of the PSU? Noise isn't a problem for the server PSUs out in our dedicated mining portion of our barn, but if we ever have any in the house it certainly would be an issue...
