Of course you never know what you are getting when you buy a refurbished computer. My last one was a bad buy, but this one, so far, has exceeded my expectations. One thing I didn't realize was is that this PC does not have bluetooth capabilities, so don't get this if you need that function. The PC set up fast and runs pretty fast as well. No problem hooking my printer up with a LAN cable either (since I couldn't connect with bluetooth). Packaging was outstanding and could come in handy if I were to need to ship something out in the future. It runs on Windows 10 Pro, which is closer to Windows 11, but you cannot upgrade this PC to Windows 11. It does not meet the minimum requirements. DVD drive seems to wotk fine. Having some prior PC knowledge will help, because this did not come with an hook up instructions or anything to explain all the ports on both sides. You will have to connect the wifi antenna up in the back. You will see 4 USB ports, the one under the blue, round PIN connect port is the one to plug this into.
