Sell gaming notebook? What else can I get?

I bought a gaming notebook at the beginning of last year. Now I wanted to sell this to buy a normal desktop. What else can I get?

there are hardly signs of wear, original packaging and invoice, but it has already been opened (warranty still exists)

Purchase price was 1099 euro

The notebook:

So I think with much luck 700 euro maybe.
