I have a SONY NEC - AD7590s Slim DVD Writer (Internal).
Need to know how to connect this to a desktop / 1U Rack Mount chassis.
I am working on something similar (that's how I came across this thread), but with a slimline, slot-loading, ide drive. After many hours of looking around, I've concluded that the only place that makes the mounting hardware you are looking for is here: http://www.slidirect.com/Products/Custom-Bezels_2
Because the drive gets it's power via the interface, you will need this sata/power cable kit: http://www.slidirect.com/Products/Adapters-and-Cables
I think that will get you where you want to be.
