Accidentally Took Off Reset Button Off Of Front Fascia (Corsair 230T)

It did cross my mind that perhaps you can simply repair the damage by re-seating the button?

As for the rest, you may be able to bring stuff over from your current fascia.

Finally, Corsair (or their forums) will have a definite higher probability of knowing exactly what goes with their stuff than the chances of someone here knowing exactly what you need to know.
