Designed to support a wide range of motherboard sizes including Mini-ITX, Micro-ATX, ATX, and E-ATX (up to 305mm x 277mm), the 4000D caters to many build types, including compatibility with reverse connector motherboards from ASUS, MSI, and Gigabyte. Its modular FRAME system architecture facilitates extensive customization and future upgrades to components like the motherboard tray and front I/O.

Key cooling features include dual 360mm radiator support on front, roof, and side mounting locations plus compatibility with up to ten 120mm fans simultaneously, making it perfect for high-performance liquid and air cooling setups. The case accommodates graphics cards up to 430mm length, CPU coolers up to 170mm height, and power supplies up to 220mm length.

Additional conveniences include a GPU anti-sag stabilization arm to preserve PCIe slot integrity, a tempered glass left side panel to showcase your build, a steel right panel for rigidity, and comprehensive dust filtration for cleaner internal components.
