I guess the same people who are buying FIAT 500s and getting this

Ah people who buy an overpriced and less functional Fiat Panda and are than suprised that it's still typical italian quality (read that car sucks donkey rear)....
The pseudo retro blitz will only get you that far, unless your product is good enough to stand on it's own (if BMW had named the Mini "0-series" combined with a modern looking body-kit, it would still be a success cos it's actually a quite good sporty small car).
So no, putting a bottom end PC into a retro case that has serious useability-issues isn't gonna sell wll once the blitz is over.
