Help please💕

Hello everyone, I hope it’s okay to post this here even though my question is about a prebuilt pc… I don’t really know where else to ask this.😅 I have this pc in the picture. I am selling it to my friend I bought it 2 years ago I think. I have been travelling all last year and this year so I used it only about a year. I don’t really know how much I should ask for this? Please help, what is a good price?

Thank you so much💖
