Stripping it for parts? Well, there's a HD and a BluRay, of course, and a fan, and some cables; those would be worth a few bucks put together.
Beyond that there's a couple of circuit boards with lots of chips soldered to them. If you have a BGA rework station and a steady hand, you could recover the ICs. But if you're looking for a graphics card, a socketable CPU, memory DIMMs... you're out of luck. There's no reason for MS to make the xbone a PC on the inside, and every reason for them not to.
