NUC for ROCK clarification needed

I’m going to sell my ROCK Nuc at some point fairly soon and will put up for sale on here. Any idea what I should charge for it, I’ve not got a clue? Not looking to make a killing, just looking for a good home.

The NUC is an Intel NUC BXNUC10I5FNKN2 / Core i5-10210U, 2x DDR4 Frost Canyon

Cost me £400 from Amazon in December 2022.

It has 16GB memory, made up of two x 8GB.

Less? More?
