It depends if you want the images or previous versions of wikipedia too. The current version is about 25Gb compressed, the dump with all versions is aparently multiple terabytes. They don’t say how much media they have, but I’m guessing it’s roughly “lots”.
The English Language Wikipedia probably wouldn’t be hard, or Debian Stable.
All of Debian’s packages might be a tad more expensive, though.
This might be a good place to start for Wikipedia;
https://meta.wikimedia.org/wiki/Data_dump_torrents#English_Wikipedia
And the english with no pictures is even smaller
And you can use Kiwix to setup a locally hosted wikipedia using the data dumps
