Microsoft Xbox One Repairability Score: 8 out of 10 (10 is easiest to repair):

Only a few tools are required to take the whole console apart. The opening procedure is similar to, but much easier than, any Xbox 360.

Once inside, a clean, no-nonsense modular design allows the drives, fan, heat sink, wireless board, and front daughterboard to be easily replaced.

Clips instead of screws make opening the case more difficult than necessary, but the absence of adhesive and proprietary screws helps soften the transgression.

The hard drive is relatively difficult to access; you'll have to void the warranty if you'd like to upgrade/replace it.
