A family member of mine in Germany is looking for a laptop in the 100-200€ price range. It would be okay to buy used and it shouldn’t be one of those modern Celeron laptops. It should still have a fairly slim design and a processor at least good enough to run Minecraft at low settings with ~30fps on Linux. Is this even a thing, and where would be the best place to start looking?
You can get Lenovo x1 carbon pretty cheap with pretty high end cpu on ebay. Don’t know if it can handle Minecraft though. Absolutely nothing with a discreet graphics card will fall into your price range. I would recommend your relative keep saving until they can spend a little more.
Something like this checks all your boxes except probably Minecraft. You can’t have it all in this ultra budget category.
It really doesn’t need a discreet graphics card I myself have a Lenovo ThinkPad L540 which has pretty good performance and can handle minecraft good enough, but my relative really dislikes how thick and bulky it is. Is there maybe a thinner laptop in that range with similar performance?
Absolutely not. The carbon is already very slim. It really sounds like they want a MacBook which we both know is not gonna happen for 200. Your relative needs to come to grips with the reality of their budget or just keep saving. Best time to buy is after Christmas when people get new shit and sell their old stuff.
