I don't have very strenuous computing needs but my windows 7 machine had past its prime. I needed a replacement for personal use and work. Mostly involves browsing, spreadsheets and I do some light music recording. This machine does exactly what I needed it to do. Mine came super clean with the exception of the fan so I opened the case and blew it out with compressed air before turning the unit on. All of the dirt vanished and the motherboard as well as other components were already clean as new. No visible wear on the tower either.Fired it up and went through the setup procedure which took maybe an hour (mine came with a key and Windows 10 Pro). It's been a week and I have had no issue at all, runs fast and quiet. Would recommend it for sure.
