iFixit is back at it again with a new teardown, this time taking apart Microsoft's revamped Xbox One S game console. The deconstruction of the Xbox One S reveals a much tighter design, which allows the system to occupy 42 percent less space than its predecessor.

The outer shell of the Xbox One S is held together with security clips rather than screws, revealing a inner metal case. Under the metal shell are the tightly packed components, including an optical disc drive with a bracket featuring a small Master Chief imprint.

One of the more notable changes moving from the original Xbox One to the Xbox One S is the internalized power supply, which is fanless and accepts 100-240V inputs. It sits neatly among a Seagate 2 TB hard drive (in the highest-capacity model) and a Philips/Lite-On Blu-ray drive with support for UHD Blu-ray.

The Xbox One S' mainboard, which features the AMD Jaguar APU, is cooled by a custom aluminium heatsink with copper heatpipes and a 120mm fan. The board itself features 16 Samsung DDR3 chips, for a total of 8 GB of RAM, along with 8 GB of Toshiba NAND. It's supported by two breakout boards, which add Bluetooth for the controllers, Wi-Fi 802.11ac, and infrared.

In the end, iFixit gives the Xbox One S a good repairability score, noting that it only takes a few tools to deconstruct the entire console, and many internal components are easily replaceable. However, replacing or upgrading the hard drive is a little tricky, and it still only supports SATA II, which limits solid state drive performance if you decide to make that upgrade.
