Pffft. Open box, used, refurbished. All of these had some kind of issue, which is why they were returned. I'd NEVER purchase a graphics card that fell into any of those categories. Too much risk, not enough reward. Not worth saving 30 bucks to roll the dice on not having the same issues that the person who returned it had.
If you can't buy a card new, don't buy a card. Save the money up until you can get a new card with a full warranty. And unless I was buying it from somebody I trust well enough to invite to my mother's house for dinner during the holidays, I wouldn't buy ANY used card, ever. That's just my opinion, but I see too many people get ripped off buying used hardware to believe it's worth the risk.

2GB ram is too weak for games
That's your opinion. Not everybody can afford to get what they really would prefer to have. Some people have to make due, and a 2GB GTX 1050 would sure as hell be a far cry from any model of GT 1030. Plenty of people with realistic expectations making due with GTX 1050 cards all across the world. Must work for them. I guess not everybody thinks they need to have the texture and a few other sliders all the way to the right. If you make allowances, and have realistic expectations, any half decent card is better than none.
