I just received it today, unpacked and turned on (plugged in the wifi adapter before turning on), the installation was smooth and fast, the computer looks like new, no scratches, nothing indicating its a refurb, and was up and running in 10 minutes or less. It is super-fast and everything works perfectly. I will try to update my review in one month. The wifi-adapter is only for 2.4gb, so i may need to buy and replace with a 5g, but its minor as i dont feel yet if it affects the speed. It also came with a display adapter to connect via hdmi, and works perfectly with my sceptre 23.8 monitor. i might need to buy another adapter for my second monitor. I will use this pc for remote log-in to my work's network. The pre-installed windows 10 pro works well; it is potentially upgradeable to windows 11 after switching to secure boot settings (instructions on windows11 website), but i dont need it yet. I am very satisfied with my purchase, for the price, its unbeatable.Update May 2022: 5 months later, still going strong. Works perfectly, very fast computer. I am very happy with this purchase.
