In galaxy clusters cooling from the intra-cluster medium provides the cold gas which fuels the central AGN and thus maintains thermal balance. We also see evidence of such cooling in massive X-ray luminous groups. However some lower luminosity groups have central galaxies which are actually richer in cold gas despite their lack of cool cores or active radio jets. We propose to observe two such systems with the goal of determining the properties and dynamical state of the intra-group medium measuring their cooling rate and searching for evidence of old AGN outbursts. Moderate exposures will provide order of magnitude increases in depth over the available observations for these groups giving us new insight into the origin of their cold gas reservoirs. [truncated!
