This was an excellent purchase as a second PC. I was not looking for something to run too fast or for a lot of storage. This Dell is excellent in that it does have USB 3.0 and plenty of USB ports, it is small enough and powerful enough to run smoothly. It has sound but I also purchased an external speaker for better sound. It came with a mouse and keyboard. Loved the keyboard that looked like it was a protected type of device. This device also has a DVD drive that is very useful for me since I still watch DVDs. With Dells you are able to download their SupportAssistant to keep your unit optimized so I use that and this device is just excellent! Runs very fast and is a very clean PC. It also has tech support if needed. I use it with a CAT6 direct connection to my router although it comes with a WIFI dongle. That needs to be upgraded. It is a slow one but it works. I may, later on, upgrade the network card to make that faster but no need now.
