So I would adjust fire on the challenge to find out what absolutely cannot be sourced from outside China.
Ideal = Build a complete system where all parts are not manufactured in china and do not use chinese parts - this included Case and all components of the PC as well as all Inputs and Outputs
If a component cannot be made without parts from china state why or what cannot be sourced - Even if a 100% no Chinese parts PC cannot be made it would be very interesting to find out what it is that can only be sourced from China.
Expected outcome - a full PC that can run a modern operating system and at least play games on steam. I would say those games would not even have to be fully 3d.
