Key benefits Expands front USB connectivity: converts motherboard USB 19pin and USB 9pin headers into 2 USB 3.0 ports and 2 USB 2.0 ports on the front panel. Frontpanel accessibility: mounted in a 5.25inch optical drive bay to provide convenient front USB access, eliminating the need to reach behind the PC. Simple installation in the optical drive bay: designed for installation in the idle optical drive position of the chassis. Audio behavior unchanged: the audio signals are pulled directly from the motherboard; the panel does not modify or improve sound, and sound behavior depends on the motherboard and playback device. Speed caveat: when connected to USB 2.0 headers, USB 3.0 devices will not operate at USB 3.0 speeds. Installation considerations: before , check the optical drive bay mounting holes in the chassis. If the holes are elongated, installation is straightforward; if they are round, verify the size to avoid uneven mounting and potential trouble. What you get and compatibility Provides 2 USB 3.0 ports and 2 USB 2.0 ports on the front panel. Connects to motherboard USB 19pin and USB 9pin headers. Intended to be installed in the 5.25inch optical drive bay area of the chassis. The panel relies on the motherboard and its headers for speed and function; it does not add wireless or other features beyond the stated front USB interfaces. 23 practical use scenarios Gaming or multimedia PC with many peripherals: use the front USB 3.0 ports for gaming mice, keyboards, external drives, and VR gear to avoid reaching behind the case. Home theater PC or media center: keep USB devices like remote receivers, USB dongles, flash drives, and media controllers easily accessible in the front bay. Workstation with multiple USB devices: reduce cable clutter by placing frequently used USB devices at the front, while preserving rear USB ports for less‑used devices. Notes If the panel is connected to USB 2.0 headers, USB 3.0 devices will not achieve USB 3.0 speeds. When , verify the chassis optical drive bay mounting hole type and size to ensure proper alignment and installation. If the holes are elongated, installation is typically straightforward; if round, confirm the exact size to avoid mounting issues.
