Get all the CAD files and other specifications here: http://opencompute.org

One of the most important fact form this article which is likely to be overlooked is : "the Prineville facility runs at 85°F with a 65 percent relative humidity". Running at such a high humidity + Temp combination is impressive esp when you look at the money saved in environmental costs.

That quote made it seem like the incoming air was at 65% relative humidity, but...

"which in turns lets Facebook rely on evaporative cooling instead of air conditioning."

So it runs at 65% relative humidity after the swamp coolers.

I doubt this would be possible in datacenters in more tropical environments (south Florida). Thoughts?

Any idea on how much would it cost to produce a small quantity of those boards? At which scale does it starts to make sense to use a custom made motherboard instead of a off-the-shelf PC?

HP, Dell and other vendors are already showing off hardware built to the new specifications: http://instagr.am/p/C66FU/

Your link does not support your assertion. It's just a picture without a caption.

With a source fairly prominently displayed at the bottom. Follow along if you absolutely must know more:

    1. Navigate to twitter.com/scobleizer.
    2. Observe first tweet.

That said, I lost all interest in the image due to the dumb focus effect.

ditto on the focus effect. reduces the value of the photo.

"Process journalism" at work.

One thing to keep in mind is that one rack holds 90 servers and each battery rack feeds 180 servers, so (at least in Facebook's case) that's the basic unit. If this stuff takes off I would expect someone to produce a smaller 30-slot rack, though.

No. Each rack holds 30 servers and each triplet holds 90. The battery cabinet can support 2 triplets.
