I could not be more pleased. Unit was promptly shipped and came with a new keyboard and mouse. Win10 Pro was a brand new version 1909 with a new product key. Unit was new in 2016 and there was not a wisp of dust on the inside. It had BIOS Revision 1.6.1 which I updated to 1.12.3. Just go to Dell.Com Support and enter your Service Tag Number. I replaced the 500GB 7200RPM drive with a Crucial 500GB SATA SSD for 50 bucks. Cloning was simple - I used the free Acronis software that came with the drive and hooked the new SSD to the computer using a 10 buck USB3.0-To-SATA cable. Boot time from power-on to WinLogin was reduced to about 15 seconds with this i3 processor. Computer did not come with WiFi capability as advertised so I spent 20 bucks and bought a good Dual Band USB3.0 WiFi Dongle. It was the only way I could activate Office 2019 Home & Student  otherwise I did not need WiFi capability. Again, I am just really pleased. The Optiplex 3040 Micro is just a beautifully designed tiny computer that is easy to work on.
