I bought this not long ago.
It has the headset, two sensors, and two controllers.
In excellent condition.

I ran this previously on an Intel i7 920, 8GB ram and a Geforce GTX980, and it all worked fine (I upgraded with second hand stuff, but still have the 980 and it's perfect). I know nothing about PC specs, but learnt a bit before getting one of these.
You'll need at least one 3.0 USB, but one sensor can use 2.0 (you don't need two sensors, but precision is better). The headset needs HDMI, or get those DisplayPort/Thunderbolt adapters.
