thats a good question, but after looking at pictures on the almighty internet (dangwang blog), the mx mini as it was sold relied on mounting to the case via the plate it uses. it did look to have pcb mounted stabs though
the race attaches to the tray from the PCB itself, there is actual proper mounting holes for the tray on the PCB because the RACE doesnt have a plate. If you are familiar with the way the poker or pure attaches to a tray that is the same with the RACE
now if the replica has new mounting holes that match the race tray, as well as a different mounting location of the USB port then yes it would be compatible but i seriously it was the intention of the replica to make it work with a RACE tray.
