The Front Panel
The front panel of the SilverStone Redline RL04 has four external 5.25” bays with solid covers. There is a 120 mm fan with red LEDs at the bottom part of the front panel, and it is possible to install a second 120 mm fan or a 180 mm fan (if you remove the 120 mm fan that comes with the case). There is an air filter for the front fan. The manufacturer doesn’t publish the technical specifications for the fans that come with the RL04.
The case comes with two USB 3.0 ports and the traditional audio jacks installed on the left side of the front panel. The USB 3.0 ports use an internal connector.
