reviews come in white or grey. Early pre-dated xenons come in XDK grey, though when the 360 went through out its life, blackish grey was dropped and white carried on for demo/review kits.
Ok so this demo kit mystery is bothering me, i just want to know why does it have demo sticker on the case but it has all the pins for a sidecar.
It shouldnt. Almost every demo, test, full dev and stress kit will have several pinouts and headers a retail console will not. On full dev and test kits, they are intended for a sidecar. On stress kits they are intended for stress cables to be connected to something referred to a a lamprey board, basically a dev version of a nand-x to be able to easily flash and reflash the nand as necessary. A demo kit is nothing more than a stress kit without the cables and traditionally appearing very retail like, ie no cables, no sidecar. An early kit referred to as a reviewer kit is found in all black and is marked as such by a small decal at the back. These were replaced after 2005 by the now known demo kit. Anyway, the demo, stress and reviewer kits almost always are lacking the sidecar power supply pinout which is a two pin set near the psu port by the rear fans. Because of this it's not possible without modification to connect a sidecar to a demo, stress or reviewer kit.
yea i know but this demo kit has the 2 pin out near the psu port. Edit: you can see it in one of the picture.
Well i have heard of some being recycled much like the debug kits of the OG xbox used for the beta testing. This may be one of them. Nice find.
