Unfortunately, this is wrong.
People are not joking when they call the machine unusable, even for the simplest of tasks. I owned one for 4 days and had to return it. The most taxing activity I engage in is watching YouTube videos. It was unbearably slow, even for activities like opening a folder or browsing the Internet. Bar none, it was the slowest and most frustrating computer I have owned in my entire life. The lady at the Apple Store told me "everyone returns them".
It is a dreadful machine and should be avoided completely. There is nobody I would ever recommend the base model 2014 Mac Mini to. Nobody.

I would avoid that machine entirely. And I certainly wouldn't burden someone I care about with that piece of junk. It would be like giving somebody an iPhone 3GS today.
If you do buy one, the external SSD will be absolutely necessary. But even then you are asking for trouble with 4GB of RAM. That level of RAM is already obsolete. I can't imagine the problems it will cause 2 years from now.
