Is this Mac G5 a Xbox 360 dev environment box?

Of course, as usual we can’t speak to the validity of the photos in question (we wouldn’t be doing our job if weren’t at least a little skeptical), but it sort of makes sense for them to be using a Mac G5 as an alpha for the Xbox 360/Xbox 2’s dev environment kit, as the console is supposed to be running a tri-core version of IBM’s PowerPC processor. The G5 in question is also supposedly equipped with that ATI R420-based adapter and a paltry 512MB of RAM. It also makes sense that the stickers refer to it as the “Xenon”, since Xenon has been confirmed as the console’s codename. Real or not, some stickers slapped on a G5 is still not nearly as impressive as that Sony PSP dev system we saw before.
