To Build Or Buy?

I have a 2018 Macbook Air. I am considering building an eGPU.  I would like it to use the OSX system and the internal display.  Perhaps Catalina will make that easier.  Anyway, are all the necessary parts available and is it doable?   I read somewhere that there  might be some proprietary parts that I can't purchase. Thanks.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@engine44 The 2018 Macbook Air has Thunderbolt 3 ports so it should work no problem with macOS.
