We will present Chandra observations of 4 giant elliptical galaxies:NGC1399,NGC1404,NGC4472 and NGC4636. We have determined the spectrum with position deriving temperature and abundance profiles, cooling times and mass accretion rates. We place strong upper limits on the presence of a central point source strongly bounding accretion onto the central massive black hole. We will present spectra, luminosity functions and time variability information on the rich x-ray binary population in these objects. For NGC4636 we will discuss the very unusual spiral structure seen in the x-ray image.
