A bucking converter of that size would probably end up costing you far more than what you paid for that server psu assuming you didn't pay all that much for it. (and I don't know where you'd get one) You'd probably be better off just selling that thing and buying some standard 12v power supplies.

I recently acquired some interesting server PSUs, and have been wondering whether I could put them to use. The problem is that they produce 48VDC, not 12VDC like most of us are used to. The even larger problem is that they are MASSIVE. Here are the specs:
18KW total (Yes, 18,000 watts) per enclosure, with each enclosure holding six actual hot-pluggable PSUs. The enclosure is divided into two banks of three PSUs, rated for 2950 watts each at 51.7 VDC.
200-240 VAC autoranging input at 50/60 HZ.
3 phase (aprox 75 amps total at 240 VAC)
Here, have a pic:
Wonder if a 48VDC to 12VDC PSU could maintain high efficiency and be useable to power mining rigs.
P.S., I already asked about this on an RC airplanes forum, but the max they can use is something like 32VDC and I can't find an appropriate buck converter anywhere. My next place to ask will be on an electric-car website....
