Microsoft's Larry 'Major Nelson' Hryb has posted a "totally unofficial, but very cool" 3D rendering of the Xbox One that let's you get up close and personal to the next-gen console. While it's not the same as actually seeing it up close in person and feeling it with your own hands, the rendering does provide a nice option for those who just want an overall idea as for the shape of the system and controller. It's also kind of neat to see where all the vents and input ports are.
Feel free to play around with the rendering below. Get in there nice and deep like.
