Re: Trade in
Having said that, my Proliant Microserver has held its value better than anything else. Bought it in 2013 for £160. I could sell it on eBay now for £200.
I think this is because HP have lost the plot with their Microserver range.
I bought a Gen8 (I think it was) in 2016. After cash back it cost me £80. Ok, it had no drives but it was £80 including an iLO4.
When I checked the Gen10 about a year or so ago they were averaging somewhere between £400 and £500.
You could buy a more traditional mini tower with much greater performance for the same or even less.
