just scored one from BB and the mfg date was 12-9-05 with the remote. power supply was a dark grey putty color (almost black). hard to wrangle the power cord wire as its pretty thick to try and get some organization to the wires behind my TV.
so far no lockups. have it placed on a OPEN on all 4 sides entertainment stand. hopefully enough ventalation for both the xbox, the power supply, and the PVR and DVD upscalling players.
