I live in a nice apartment downtown so I don't have access to a place to work on my car/computer/whatever, so I don't have a space to use a dremel quite unfortunately.
However, With a little creative placement of wires, one can manage to arrange the cables in a way that is at least somewhat organized.
It's a bit of a mess in front of the bottom HDD cage, but the airflow from the 120mm fan is still strong. My top cage is empty, and the fan blows directly at the video card and CPU HSF. All I need now is a new video card and I've got a pretty decent machine IMHO. Sigh... I really want to hold out for a 8900/R600 but it's pure torture I tell you! The 8800 calls to me in my dreams!
