Box contained the refurbished mini-computer with power cord/DC converter and a new USB keyboard and USB mouse. I have a Lenovo dock that would not work with my old Linux server. This HP 600 G2 comes with a USB-3.0 C port, and it does connect to the keyboard/mouse/LAN that are connected to the dock. But it does not connect to a display that is connected to the dock. The display works fine connected to the VGI port on the mini-computer. I did not try the Display Port output.The built in WiFi worked (no WiFi dongle with mine... built in) - I did not try Bluetooth.The fan runs quiet.Windows loaded just fine, and I overwrote it with Ubuntu (Linux) 22.04.3 and it's working fine for the week or so that I have had it. Hope it works for several years.
