While not all reviews had the same experience I did, the keyboard, mouse, and computer looked brand new. I popped the cover off the computer and it was pristine inside. The only thing that was wrong was that one of the two posts to secure the monitor cable to the jack was missing. I just took one off the old computer. The computer booted up and configured fine. I ran Dell's SupportAssist software and there were three updates needed, two critical security updates and one recommended video update. All installed fine. Dell also says the unit went out of warranty in August 2020, for whatever that's worth.When I ran the Dell Hardware Test it said all was well but the hard drive gave a WARNING icon. Yet the details of the test said the hard drive was fine. I dunno...EDIT: Now that I've used it several days I did find one other problem. There are four USB ports on the rear and four USB ports on the front. One port on the rear does not work. Anything plugged into it gives constant "device malfunctioned" error dialog boxes. I disabled and re-enabled the port in the BIOS to no avail. Device Manager shows no errors. The computer this Optiplex replaced only had four USB ports and I still have three unused USB ports so this is not a problem for me.And I even got a bonus! WindowsUpdate said this hardware CANNOT be upgraded to Windows 11! :)The I5-6500 CPU and the TPM v1.2 are not acceptable for Windows 11 and I'm good with that.Bottom line: This was a great deal for me.
