Decent Laptop for 400-500 Euro for Student/Light gamer?

I'm a 10th-grade student from Greece planning to buy a laptop. Right now I have around 450 euros but I'm sure I can get it to 500, and of course if there is a good deal I'll pay less. What I'm looking for in a laptop is:

a relatively bright screen with ok colours, that's not too small

decent CPU for the price

preferably 16GB ram (or the ability to upgrade it myself)

decent battery

good build quality.

Personally, I have a general trust in Lenovo laptops as they're definitely the quickest and most durable of any laptops I've ever used, but other brands obviously are considered if they're good.

I've done a bit of research myself and found a couple of laptops which are in my opinion really good deals for what my intentions are (light gaming, 6+ hour usage, school work, light programming, MUN)

There are two options, please excuse the fact that the pages are both in greek, I'll list out some of the most important things to know here
