It's a response to the emails they received after demoing a Colossus with green lighting at Gamescon 2010.
"After releasing Colossus, BitFenix fans from around the world offered their own personal suggestions on some new and interesting modifications for the full tower, and Colossus Venom and Colossus Window are the results of that feedback," says David Jarlestedt, BitFenix Product Manager.
The Venom lets users switch between red and evil green lighting for the tower, while keeping all the traditional Colossus features, including a pair of SuperSpeed 3.0 USB ports, a storage compartment, and the company's proprietary SofTouch coating.
