i have seen that pic...i think that one had a dual processors as wellHahaha
I have seen that Beas before and would take it off your hands. Not sure what I would build with it, but the top airflow is cool. Best I could Dig up is that it was just called plain "ALX"
I do know that after 2004ish they switched to the plastics Predators, and predator 2.0. My predator 2.0 came with some chrome paint on the silver fins, and was dubbed the ALX edition.
I would assume that your case was simply called an Alienware ALX, due to it being a top of the line case holding TOTL parts.
