A Blu-Ray drive to add to the MacBook 7,1? I am working on downgrading my laptop to make some extra money while having a beefy Windows PC for gaming, VR and other things...and I just really need a laptop for the go, and decided that the MacBook 7,1 was most appealing to me.

Since I can upgrade it with RAM, SATA drives and even it's ODD, I wondered if there was a way to plop a Blu-Ray drive into this? I would like to watch some DH Blu-Rays sometimes. Most of my anime collection is physical, therefore I need a physical drive to play them back.

What drive can I get to do an upgrade?

Which internal Blu-ray drives are compatible with a unibody Macbook Pro?

Be aware that the OS itself won't play back BluRay movies; Steve Jobs was on the record as saying that BluRay's DRM were "a bag of hurt". The linked question has among its answers a link to a supposed workaround for this, but that link no longer works.
