Month old acer mixed reality headset very good condition still in box and still under warranty.
Min specs listed for are a gtx 960 and a core i5 you also need a usb 3.0 socket and Bluetooth 4.0 to connect the controllers.
I used a Bluetooth usb dongle off amazon cost 7 pound and worked fine.
You also must have windows 10 with the latest updates.

You can now play steam VR games on these headsets steam auto installs the required programs.
