CPU cooler height limitation
When optical drive is used, the GD04 has 70mm height limitation for CPU cooler. If no optical drive is installed, the height limit for CPU cooler increases to 120mm
If a silent CPU cooling solution is required, we recommend using the SilverStone NT01-E in fanless configuration for 65W rated or lower CPUs.
