This server is still functional but is based on Microsoft Windows Home Server Ver 1, itself based on Windows Server 2003. This listing is posted on Craigslist, OfferUp and multiple Facebook groups. I have two servers for sale right now. The person who buys the first also gets a free APC NS1080 UPS. Batteries still working though I don't know how long they would provide power.
