if i installed Mojave on a laptop that has no support online what features would probably not work?

i want to try to install Mojave on my 5 year old laptop, what would probably not work?

it has an 3rd gen i5 and a gtx 630.

i know that i would have to change the wifi and bluetooth modules for some macOS features to work... what else? usb, headphone jack, keyboard, webcam, trackpad, ethernet...etc

this is just a trial run because im planning on upgrading my laptop and want to know how feasible it is to install macOS on a laptop that has no support online.
