I bought this about 3 years ago. It arrived in good condition with OS installed. Easy setup and silent operation - and it performs. Very happy for about a year, then it started spontaneously rebooting and eventually not starting at all. I tried to contact the vendor as it was still under warranty and never got a response. So it is now on the  junk shelf and will probably build my new system myself to reuse the SSD and memory. So much for relying on a warranty - might as well build the next system myself.
