Nintendo classic mini NES Repairability: 8 out of 10 (10 is easiest to repair).

Only standard Phillips screws are used.

No breakable plastic clips or strong adhesive is used.

Many components are modular including the button board and controller ports.

The NES Classic ships with solid state games, this reduces the wear on the device, but means upgrades are probably not an option.

The HDMI and USB ports are soldered to the mainboard which makes for a more complicated repair.
