Processor Intel i5-6300HQ

Hard drives: 256GB SSD
500gb HDD
Windows 10 Home operating system
8 GB RAM
Think 150-200 euro would be fair.
I would estimate a maximum of 200 euro…
Should work.
Best price range xD
So 200-250 euro with a little luck should be possible.
Because the Intel i5-6300HQ is a real quad core; also based on Skylake, and the GTX 950m at least represents a somewhat underclocked GTX 750Ti (desktop), with a completely overhauled condition and battery remaining power of around 50 to 60%, I would still at least fair around 275 to 350 euro in the private / to See private sales for it with Win 10.
An AMD Ryzen 3 - 3300U including Vega6 - iGPU, on the other hand, would not see a country, and a book with a modern i5-8xxx / 9xxx - quad core from Intel with 4C / 4T without SMT and GTX 1050m would not be noticeably faster than your book.
The higher estimated value, of course, only if the battery was still (significantly) over 50 to 60% of its nominal capacity.
