Looking for an Laptop

LAPTOP QUESTIONNAIRE

Total budget (in local currency) and country of purchase. Please do not use USD unless purchasing in the US:
400–500€, Germany

Are you open to refurbs/used?
Yes, used/refurbished is totally fine

How would you prioritize form factor (ultrabook, 2-in-1, etc.), build quality, performance, and battery life?
Build quality + durability are most important, then performance, then battery life

How important is weight and thinness to you?
Not important, can be heavier if it’s more durable/performs better

Do you have a preferred screen size? If indifferent, put N/A.
N/A

Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run.
Programming (Arduino, engineering-related software), light 3D work, general school use, gaming

If you’re gaming, do you have certain games you want to play? At what settings and FPS do you want?
Casual gaming, modern games should run at least on medium- good settings with playable FPS

Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)?
Very durable build quality is important, good keyboard preferred, reliable long-term use

Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion.
I’m unsure whether to go for a business/workstation laptop (like ThinkPad or Dell Precision) for durability, or a gaming laptop for better performance. I want something that lasts and can handle both school/programming and some gaming without falling apart quickly.
