The cube is in perfect working condition. Has been lying in my house not being used at all.
You get 7 boards (instead of 6).
3 boards are fully functional.
2 boards need minor soldering work. 2 remaining boards I have no idea what's going on.
So, out of the box you get 15-18 GHS with 3 boards. Quick solder work and you will get 25-27 GHS out of this cube.

Second image: 2 boards that need quick soldering have this capacitor/resistor (whatever you call it!) that fell off.
