Title:	Far-IR Spectroscopy of Extremely Luminous WISE-selected QSOs
Topic:	Extreme Sources
Abstract:	I will present some results of our far-IR spectroscopy of a sample of WISE 24um selected, luminous QSOs using Herschel PACS. We detect far infrared fine structure lines, [OI] and [CII] from neutral and ionized warm ISM. I will describe the implication of these observations.
