It was delivered on time and was in like-new condition as advertised. It has a smaller footprint than a full-size desktop which I had concerns about before I got it. However, once I opened the access panel, I was impressed. It has a recessed latched pull handle that removes the whole access panel exposing everything and no screws to unscrew or lose. Inside, not a speck of dust, literally, like a new computer, you can't tell that it's renewed/upgraded.Even though it's smaller everything is easy to see and get to so if you need or want to do anything inside it's awesome. You can see everything and get to it with ease. You don't have to be a contortionist or have tiny hands and fingers. The drives and optical reader (DVD) are contained within a rack that you just pivot upward to release and you have full easy access to them. Additional expansion slots to add what you like. If you should want to increase RAM from 16 to 32 GB there is nothing around them so removing and replacing them in the slots would be effortless. I was surprised how cool this computer runs even when using multiple high resource software at the same time with no lag.As for the USB Keyboard and Mouse, USB WiFi Adapter. These are low cost and just so you have something. As low cost as keyboard and mouse are I really like them. If you use something else don't throw them out as others have said. Save them as an emergency back up or give them to someone. I have a Logitech wireless keyboard and mouse but still using the ones that came with this computer. USB WiFi Adapter isn't the best it's not real fast and not great for long-distance so I did buy a better one at the same time. There are a lot of cheap USB WiFi Adapters that stop working after 2-3 months but here is a low-cost $17 good one I use so can avoid the hassle.Just search amazon for -TP-Link AC600 USB WiFi Adapter for PC (Archer T2U Plus)- Wireless Network Adapter for Desktop with 2.4GHz, 5GHz High Gain Dual Band 5dBi Antenna, Supports Windows 10/8.1/8/7/XP, Mac OS 10.9-10.14It increased my transfer speed from 300 Mbps or less and 3 bars signal strength to a transfer speed of 433 to 490 Mbps and 5 bars signal strength.All you have to do is connect a monitor, the keyboard, mouse, and USB wifi adapter and power up. You do need to set up you user account like any new computer. This is Microsoft so it wants you to use a Microsoft account to have a better "online experience". But all you need to do is enter your login for a Microsoft email account or create one during set up. That step requires connecting to the internet and entering the password. Or you can create an offline user account like the old days. The rest of the setup questions are about your preferences and you're ready to go.Windows 10 Pro works perfectly. My daughter got one of these a while ago and wouldn't stop praising it so I got one. She gave me a heads up about the USB WiFi Adapter solution too. I couldn't be happier with this purchase.
