BlackBox X32 + X&Z Conversion

Hi I made the choice to buy a Vevor evaluation 4 8080 cnc machine and found out after the fact that the guy had broken it before selling it to me. I have found the controller to be dead, I am planning on swapping in the open builds Blackbox x32 and I wanted to know, do I need to buy a power supply from open builds or can I use the 24v power supply from the old machine box (See included Pictures). I have also found the spindle mount to be very poorly mounted/ not very rigid or strong. I'd like to know what parts I should buy to convert the machine to use openbuild Z&X movement with openbuild spindle & spindle mount as well the extruded aluminum for the x movement is 39.5 inches across to the mounts. If anybody has the time for any advice I'd be greatly appreciative I am very new to the hobby and excited to learn.
