Lenovo thinkpad L390 , got it for uni, used for 1 year , and had upgraded it from when I bought it to a 500gb and 24gb ram , it has been a amazing mashine for computer science , it has two small cracks in the front where the trackpad is which where there when I got it and honestly they don't effect anything this is a tank. I have Linux on it now but can put windows 11 on it if wanted , I can upgrade ssd to 1tb if wanted for extra 40£ .
