Is this the PS3 developer's kit?

We can't speak to the validity of the image (as usual), but if Sony totally wanted to show up Microsoft's innocuous
"anonymous" silver developer's boxes with one of their own, they certainly knew how to do it. Not quite as nice as some of the dev boxes we've seen before from those guys (which leaves us saying nay a little more than usual) but hey, only the software companies would have to look at it anyway,
right? Oh, and what's under the hood? Well, apparently that nVidia RSX ("Reality Synthesizer") graphics chipset, and from the looks of the size, probably a RAID array of full-height drives from the late 80s.
