Advantages

The DY451L combines a robust 0.8 mm SPCC steel frame with a tempered glass side panel that exposes the interior layout and installed components. It features full-length removable dust filters for easier cleaning and extended component life, accommodates long graphics cards up to 420 mm and allows mounting of multiple radiators and up to 13 fans for a customizable cooling configuration. Front I/O includes USB 3.0, USB-C and HD Audio connections; fans are not included.

Suitable for

• High-performance gaming PCs requiring large GPUs (up to 420 mm)
• Custom builds with multiple storage drives (4 x 3.5" and 4 x 2.5")
• Systems that need extensive air or liquid cooling (supports top 360 mm and side up to 480 mm radiators)
• Silent or fan-optimized builds where users add their preferred A-RGB or non-RGB fans

How to use

Install the selected motherboard (ATX/Micro ATX/ITX) on the standoffs, mount the power supply in the bottom compartment and secure drives in the 3.5" or 2.5" bays. Route cables through the available cutouts for tidy cable management and attach fans or radiators in the preferred configuration — top, side or rear — according to the cooling parts' size. Place the tempered glass panel after verifying all internal connections. If you plan to use A-RGB fans, install the lighting components and connect them to a compatible controller or motherboard header.

Usage recommendations

Use the removable bottom dust filter for regular cleaning to maintain airflow and component longevity. When installing large radiators or long GPUs, verify clearance dimensions (GPU up to 420 mm, CPU cooler up to 180 mm, PSU max 250 mm) to ensure compatibility with your selected components.
