Banned console?

Hi , I was scrolling through eBay and I have seen a banned console for sale , and I was wondering which parts of the console can’t be used to repair other consoles , for instance could I take the IC timer chip off that mother board that banned , what about the GPU ? Or the hard drive ? Thankyou in advance

As far as i am concerned (if this is still valid question) You can’t use: CPU, South bridge and the Blu-Ray drive (Each BD Drive is cryptographically paired with the southbridge, to prevent xbox 360 type dingus.)

Blu ray drive can be used as long as you swap out the daughter board with the one that matches your new motherboard. Just requires taking out a few screws and resoldering 2 motor wires.
