I stumbled upon this graphics card:
https://www.msi.com/Graphics-card/GeForce-GT-1030-AERO-ITX-2G-OCV1
However I can't find it anywhere online. Tried Amazon, Newegg, even Ebay, nothing.

So, what's the deal with it? Was it actually released or it's just some prototype?

Whats the issue, you looking for a graphics board with a VGA output?

I still have some VGA screens but most cards don't offer that output. That said, most cards do offer a display port output- and there are lots of Display Port to VGA adaptors out there for not much money.
