If you’ve been wondering about what changes Lian-Li implemented in their commercial XBox 360 casemod called the PC-XB01, they’ve recently updated their product page.
The case does not add any new functions to the console, but it improves its efficiency on several levels. To deal with the noise produced by the DVD drive, they installed sheets of sound insulation foam around the drive, greatly reducing the sound it makes when it spins up. They did even more for temperature control, replacing the standard dual 70mm fans with a single 120mm fan that cools more efficiently and quietly. The case is also larger and features a frontside grate, allowing for vastly improved airflow. Lian-Li designers even left opening in the back for option water tubes in case you want to add a liquid cooling system.
