Default PSU for hard drives?

I'm planning / researching the idea of building a file server for use later. Basically, I'm doing it to put a use to my 23-bay server case that I have. My case can support two power supplies (already modded to have two), so I figure I'll have one PSU for the main computer parts and one hard drive, and then another PSU for the hard drives. If I max this sytem out, I'm looking at about 25 hard drives. Then there are the 12 - 15 fans in the system as well. All powered on one hard drive.

Any recommendations for a PSU to handle the +12v only load? The PSU would have to handle crossload very well, as there likely wouldn't be anything on the other rails (unless I mod that, which I wouldn't mind doing at all), and stability is of course a major concern. I'm currently thinking of something in the area of dual Corsair 620s or dual Silverstone ST75F. Excess power I have no problem with, as I can't afford to be underpowered on a machine with 25 hard drives... Oh, and I might add, that non-modular PSUs will clutter up that side of the case quickly, so modular connections are a plus.

Anyway, this is a work in progress over the likes of probably 2-3 years. Thansk for any help ya'll.

EDIT: Oh, and the RAID controller (likely the Areca ARC-1130) will support staggered spinup. And it will probably be set to 4 or 5, as boot up time will not be an issue with this machine.

Default

Hard drives draw off the 5V rail as well, so crossloading shouldn't be an issue. With that many drives i'd suggest a single 12V rail psu, so its less likely to shutdown with 25 drives spinning up at once without need to get staggered spinup working. Corsair 620w should do fine.
