It'll probably only sell for about 42 GPB. I base that on the last one I saw on the U.S. eBay website. And there was only one listed. The rest were parts.
In my opinion, Acer is not a particularly very good brand of computer or has good resale value. Dell on the other hand would be, and there are loads and loads on the U.S. eBay website. It's where I always bought my laptops as well. To this day I have yet to buy a brand new laptop fresh from the factory. And here I used to get the Dell product catalogs in the mail.
This was an old but very popular Dell TV commercial here in the states. LOL! Now there's an Internet meme: "Dude, you're getting Adele!"
LOL! I wouldn't mind Adele singing at my future wedding or something. LOL
Anyway, usually parting a computer out is more profitable. But laptops are A) not easy to pry apart for the layman, and B) it's an Acer and C) expect the parts not to sell for months at a time.
Here in the U.S. we have loads of personal for sale Ad abilities. There's a popular website called Craigslist and there are Facebook buy/sell groups. If your country has a similar Craigslist or if you have Facebook (I don't) find a buy/sell group in your area.
Again, I don't know if the market is different in Denmark, but expect around 42 GPB if you ask me. The laptop is quite old you know...
Tip: If you do sell privately using Facebook or what ever, make sure you conduct the trade in a public area like a grocery store parking lot. Also note this: In the U.S. we have counterfeit ink pens that can check if bills are counterfeit. You just mark an end of the bill and the color will tell you (At least for a certain percentage of counterfeit currency). If you have a similar pen in Denmark then buy one and use it. I don't know about your currency, but I suppose if you guys deploy holographics that would be harder to counterfeit. I say this because many people here in the U.S. have been ripped off with counterfeit money buying from personal Ads like Facebook and Craigslist. (Yeah, the U.S. has yet to use holographics. I don't know why. Perhaps it's the cost).
Edit- Never mind, we do.
Redesigned $100 bill with 3-D strip, hologram debuts today
I think now they do this for the $20 as well.
Sad but I don't carry cash hardly anymore so wasn't sure. Sign of the times...
