Comment Stolen by the FBI, not sold to them (Score 1, Informative) 67
From the way the article describes it, the FBI actually stole the group's home-made XBox-like computer. The group used stolen login credentials to get the XBox specs and built a rig to spec with parts bought from NewEgg. Apparently a group of XBox enthusiasts paid $5000 for it (they knew it was a home-made rig), but then the guy who was supposed to send it to them handed it to the FBI instead.
To summarize: Group builds a computer with same specs as XBox. Group agrees to sell it to another group, and is paid $5000. During delivery it instead ends up in the hands of the FBI.
