iFixit managed to get their hands dirty with Microsoft's new game console. The Xbox One tear down revealed one interesting feature, that its hard disk drive can easily be replaced by users, who can swap it for a drive with much higher capacity (2 TB anyone?) unit. For folks who are interested in doing so, the important information is SATA II and 2.5-inch drive size.
Also, iFixit noted that the Xbox One is fairly easy to unscrew, although it will test your patience with its 64 Torx screws, holding the entire console together. The Xbox One's repairability score is still a work in progress, but iFixit will produce a number soon enough.
