Bought a refurbished pc from amazon a few years ago (Dell Optiplex 790), had many issues with it and amazon refunded me. Last 3 years and last week motherboard died. Ordered this as replacement so I could continue to work from home. Arrived in 3 days despite it being a holiday weekend. System was cosmetically clean and was fully functional. Have been using it for a week for remote desktop. Fast boot up and zero problems so far. Came with 1 year warranty from  Skytech and ordered 3 year extension thru amazon. Very happy so far.
