This was a custom PC that was further upgraded. In full transparency, it has a bit of cosmetic wear, the rubber by the screws wore down fast. But it works perfectly well and still looks great. This comes with Windows 10 (fully activated, and you can simply connect your Microsoft account in settings) as well as a wi-fi usb adapter. There is one 3.0 USB, and 6 other USBs. HDMI, VGA, ethernet, audio input/output jacks, PS/2 mouse and keyboard on IO board as well.
