The Dell Precision 3620 Tower arrived fast and was carefully packaged. The components were present as stated in the product description. I appreciate the care that was taken in refurbishing the unit. Inside the case was clean. The Win 10 pro was very easy to set up and activated properly. The unit had the newest bios update and fairly recent windows updates. I tested the drive with a 3rd party drive testing utility and was impressed that the m.2 drive was rated as 98% good. We upgraded the nvidia card from the nvidia site (the driver on Dell site did not work for some reason). We upgraded several other drivers using the Dell support site. The only issue I had (for which I don't fault anyone) is that in the bios, AC Recovery after power shutdown was stuck in the Power On position even though it was set correctly to Power Off in the bios. The result was if you moved the unit and plugged it in somewhere the unit would immediately power On. This was corrected by toggling AC Recovery from Power Off to Power On and back to Power Off. It was necessary to bleed the power supply/motherboard so the Power Off setting would hold. For those that don't know this unit does not support Windows 11. Overall impressed with this refurbished desktop. Would I purchase again? Yes we liked so much we purchased a 2nd unit.
