...to update you all, I got the Xbox, had to buy more cables to connect it to my monitor's VGA worth 15$, and everything I see on screen is green. There is SOME blue and red, but everything is heavily green-tinged. I rechecked the cables several times over, everything is as well plugged in as can be. According to google-fu, this means video processor troubles, only repairable by exchanging the console. But of course, mine being an affordable second hand, has no warranty left on it.
So yeah, unless some miracle happens, I just blew 110 pounds on an all-greens Xbox. Yay.
