I am building a slim computer for software and game development so i can take it anywhere, anytime cause i am in college…(i do not want to spend much money, i can buy this for 500Eyros with 16GB Ram).

The GPU supports dx11 and opengl 4, is it gonna be enough for game development with dx11?

Yes that’s fine for most things. the real answer depends on how resource-hungry your game is. I’ve been using Unity on laptops for years.
