  We use molecular dynamics simulations in 2d to study multi-component fluid in
the limiting case where {\it all the particles are different} (APD). The
particles are assumed to interact via Lennard-Jones (LJ) potentials, with
identical size parameters but their pair interaction parameters are generated
at random from a uniform or from a peaked distribution. We analyze both the
global and the local properties of these systems at temperatures above the
freezing transition and find that APD fluids relax into a non-random state
characterized by clustering of particles according to the values of their pair
interaction parameters (particle-identity ordering).
