According to Google, the Banana Pi M2 Zero has the same dimensions as the Raspberry Pi Zero.

Sure it might, but unfortunately the board layout isn’t the same… and that means the Raspberry Pi Zero case that I had intended to mount the M2 Zero on didn’t fit!

I’m intending to pop on a heat sink over the Allwinner H2+ CPU, so in order to do so I’ll need to cut out the acrylic!

Pretty straight forwards!
