Last i heard the elites were the hardest to mod.
The premiums should be the easiest.
You want a benq, if you can get one with it.
Those hitachi 79f drives are the ones that require the pass-key.
Benq requires nothing. Took me 15 minutes, and i had never done it before.
And you can identify the drive based on the design of the disc-tray, but you can’t tell what drive is in the console based on the box, unfortunately.
