It only has damage to the case.
Nothing, because for me personally it has too little memory.
I can't help you with a price proposal either: /
But I would bet that it is no longer worth too much - especially due to the housing damage.
The processor is quite decent. The thing is not particularly good for gaming.
On a GTX 860M z. B. Daddling The Witcher 3 with a maximum of 40 FPS on low settings.
Personally, I would spend a maximum of 100 euro on that thing.
You could get out around 300 euro - 350 euro.
Would rate it at 300 - 400 maximum, as it would not be the first choice for gaming.
If the book were already equipped with an SSD (512 GB), and the battery is still in good shape, you could realistically expect about 300 to 350 euro from private to private.
More is not possible, because a new Acer Nitro 5 with Geforce GTX 1050 (similarly fast as the GTX 860m) with a guarantee for 700 euro is available.

There are technically about 3 years of hardware development between your book and the innards of the Acer.
GTX 860? Wait a minute, it didn't exist! The 700 series was followed by the 900 series, how can there be a GTX 860 if there was no 800 series?
There was the 800 series - but they were only mobile GPUs.
Ah! Were they already capable of DX 12, or only DX 11.1? Because with the desktop models the 700 series was DX 11.1 and the 900 series then brought DX 12. 800 series would be in the middle, don't know which DX they support.
They already supported DX12!
