I hadn't seen that motherboard pic in a couple of months. It's pretty sad really, because that does look like the Xbox One is just a box with off the rack computer parts. There was no attempt made to make it smaller, to make it sleek, nope. The MS research department probably had no time to go beyond the basic function of making a working Xbox One - and that is even now compromised by CPU upclocks that could become RROD2.
It's exactly the same situation Sony found themselves in in 2005. The OS wasn't finished, the network functionality wasn't ready, even the Blu-Ray firmware got multiple updates, the Blu-Ray and Cell tech was at that point too costly too put into a consumer device. Sony was ready for a 2007 launch, not one in November 2006, but they had no choice if they wanted to compete with MS, so they went ahead and lost a ton of money. But at least the PS3 was powerful, even if developers had to hire rocket scientists to write code for its convoluted architecture, and software can be rewritten and optimized. MS can never fix and optimize the hardware in the Xbox One. The decision to focus on Kinect 2 and go ahead with a weak hardware design will haunt them the entire upcoming generation.
