This one came from SkyTech USA. A really nice clean refurb in excellent shape. Booted up a nice new clean pre-installed copy of Windows 10. Runs like blazes with the installed SSD and 16gb of memory. Quiet as a church mouse. I hooked up dual monitors to mine using the two available DP outputs, and signed it into Office 365 and was ready to go to work in about 1-hour start to finish. I would not hesitate for a minute to get another. BTW it also came installed with Windows version 1909 so it only required very minimal updates to get going.
