Can my 8 GB Mac Mini logic board be replaced with 4 GB Mac Mini? Thanks Update (10/11/2017) Both the 8 GB 4 GB have soldered RAM onboard. Both of them introduced in 2014. My 8 GB logic board was damaged, and can’t find the replacement logic board anywhere. Is it possible to replace it with the 4 GB one? Apple Mac Mini Specs Thanks
