    from completed build Tried and True i7-950 Build

    Great case back in 2010 for the price, but with many drives & cards installed, it is very difficult to run the cables without it looking terrible. The case doesn't have space to 'grow into.' If you want to use the area behind the drive bays to run cables and plug the HDDs in from the front, you can't install the front fans. Without these fans, the airflow into the back of the case where it's REALLY needed is poor.

    -1 star for lack of cable management/ space. -1 star for the front fan issue.
