as someone who works in this, it would be kind of complex( you would have to retool, which costs a lot of money) but for apple it really wouldn't take much effort. I am assuming it's designed for ARM chips, that's why cooling was subpar, it was more of a place holder, so they can make some money.
No offence, most people who are buying this are not very tech literate, so it's fine for the audience. a older 13 inch refurbished pro is better in every way, and the same price.( can be cheaper at places like bestbuy)
