Six hard-drive bays and three optical-drive bays provide versatility. View larger. Customizable to Fit Your Needs
The Antec Three Hundred Gaming Case combines a manageable frame size with extensive options for customizing your computer or gaming system. With enough room for a standard ATX motherboard, tall graphics cards such as the NVIDIA 8800 series and the ATI HD 3800 series, six hard drives (internal 6 x 3.5 inches), one SSD drive (internal bottom-mounted 2.5-inch), and three optical drives (external 3 x 5.25 inches), the Three Hundred is a small yet versatile case for professionals, system builders, or gamers.
Top-Mounted I/O ports for Easy Access
Situated at the top of the front panel are access ports for headphones, microphone, two USB 2.0 ports, and the power-and-reset button, so you can quickly and easily plug in to your system.
Optimal Cooling Right Out of the Box
Designed for extensive use, the Three Hundred includes one 120-millimeter rear exhaust fan and one 140-millimeter top exhaust fan with built-in individual controls for low, normal, or high speeds. A CPU cut-out allows for easy installation of CPU coolers. Additionally, the front bezel is perforated for maximum air intake, and the washable air filter reduces dust buildup in your system, helping to keep your equipment cool, dust-free and reliable.
Optional Fan Mounts Increase Air Flow
The Three Hundred is designed to quickly and easily accommodate two optional, front 120-millimeter intake fans to help cool the hard drives, and a convenient opening next to the fan cage allows you to run the fan wires without obstruction. You can also install a side 120-millimeter intake fan to cool graphic cards.
Cable Compartment Provides a Clean Look and Better Cooling
Cables can be neatly tucked inside the built-in cable compartment, so you can keep your system organized and the airflow unobstructed. Routing cables is easy and efficient with the two reusable cable ties that are attached to the compartment wall.
