Corona boards require a RGH and are there for quite expensive, the Trinity, depending on the drive model a ODDE can be installed with relative ease.
I do have a Xkey left which I can build in, I'd say send me a PM with further details.
You will have to miss your 360 for roughly a week if you're going to send it to me, I highly recommend you wrap it in several layers of bubblewrap, stuff the box full of peanuts or other padding and send it tracked.
I will be sending it back in the same box with tracking.
