First one is a white elite system, which works fine (last time I used it, probably 3 years ago), but is banned from xbox live (due to modded console). Includes a hard drive and power cable.
Second one is black elite system, which works fine on most occassions, but has intermittent disc reading issues. Has never scratched a disc, but I think the reader must have debris on it, or just needs replacing. Sometimes takes a few tries to read the disc, sometimes works absolutely fine on first try. Includes power cable and componet video/audio cable. No hard drive.
