While I cant say with 100% certainty, the 9.5mm drive should fit any ASUS ROG made within the last several years.
The 9.5mm utraslim should be the same across the board. In the end, they are all Panasonic. Even if you look at the model numbers of others you will notice the same UJ-262 for the BR.
Hardest part of replacing them is taking the plastic trim off the tray of your current drive and putting it on the new one. They come with a flat generic trim on them that will not match up. Even from ASUS model to model they don't match up. Just a little patience and some small tools to release the plastic tabs. The drive is actually held in by one screw. See link in my post above for a few pictures. How much effort it take to get to the single screw that holds it in is dependent on what model you have.
One thing to note is that none of the standard players support Blu ray. Sony has those codecs locked down tighter than a goats bunghole. VLC supposedly has a solution, its open source. I messed with it for quite awhile and was unsuccessful at getting to to playback correctly, always something was hosed up. Cyberlink Power DVD work like a charm but it also comes with a price tag. Chances are if your machine didnt come with a BR they didn't include anything to play it either.
