The first-gen macbook shared a lot of internals with certain Dell laptops of the era. In 2010 I was homeless and attending high school at a boarding school and didn't have nice macbooks like my classmates, but I cobbled together my first laptop that summer from a few different old salvaged Dell models.

Dual-booting into a hackintosh was a breeze. I eventually salvaged an old T60 and it was a similar case, enough crossover in components that it wasn't any trouble running macOS.

This was in an era where you wanted Apple software even on non-Apple hardware. Today, it's the opposite.
