It's about as easy to take apart as the larger Xbox, with an even cleaner modular layout. A hard drive replacement remains the only real hassle, iFixit says. And importantly, the faster graphics aren't the only upgrade. You'll also get a slightly faster hard drive with a larger cache and an SATA III interface (at least with the 2TB model), and the newly internalized power supply should work "anywhere there's a plug." It's evident that Microsoft saw the S as an opportunity to spruce up its overall Xbox One design, even in subtle ways that wouldn't be immediately noticeable.
