It also accommodates up to seven fans, giving you the power to tailor cooling for quiet daily use or demanding gaming sessions. The front I/O panel includes three USB ports and a dedicated audio out, ensuring convenient access for peripherals, headsets, and external drives. If you’re building a versatile, future-ready PC, the MANA 137 provides the space, structure, and features to deliver a reliable, visually striking system.

• Versatile motherboard compatibility and space for high-performance components: The MANA 137 supports Micro ATX and ATX motherboards, offering builders the flexibility to craft compact workstations or gaming desktops with ample clearance for graphics cards, power supplies, and CPU coolers. This mid-tower design balances footprint with expansion potential, so you can upgrade over time without swapping enclosures.
• Extensive drive and storage capacity: With 3 external 5.25" bays and a total of 11 drive positions (6 internal 3.5" bays and 2 internal 2.5" bays), the MANA 137 is ideal for storage-heavy builds, media centers, or workstation configurations. You can configure multiple HDDs for large-scale data storage, combine SSDs for fast OS performance, and keep essential files within easy reach—all inside a single chassis.
• Robust cooling support for varying workloads: The case is designed to support up to seven fans, enabling sophisticated cooling strategies for gaming rigs, content creation workstations, or multi-drive servers. You can optimize airflow with intake and exhaust fans to reduce thermals, improve component longevity, and maintain stable performance under load.
• Accessible front I/O and connectivity: The MANA 137 provides practical front panel access with three USB ports and one audio out, allowing quick connection of peripherals, external storage, headsets, or recording devices. This combination makes it easy to connect gaming mice, USB drives, and audio gear without reaching around the back of the chassis.
• Thoughtful interior layout and build quality: Built from steel for rigidity and durability, the MANA 137 emphasizes clean cable management, easy component installation, and a tidy interior. The chassis design supports organized routing paths, ample clearance for large GPUs, and an aesthetically appealing presentation whether your build is showcased on a desk or in a media cabinet.

How to Install In Win MANA 137 System Cabinet

• Prepare your workspace and read through the case manual. Remove the side panels to access the interior and identify the motherboard standoff locations that match your Micro ATX or ATX motherboard.
• Install the power supply first if your build uses a bottom- or top-mounted PSU. Secure it firmly in place and route main power cables toward the back of the chassis to keep the interior tidy.
• Mount the motherboard using the compatible standoffs. Align the I/O shield with the rear opening, then drop the board into place and secure it with screws. Connect the 24-pin ATX and 8-pin (or 4+4) CPU power cables to the motherboard as needed.
• Install the drives: place 3.5" HDDs or 2.5" SSDs in the appropriate internal bays and use the provided mounting hardware. If you plan to use external 5.25" bays for optical drives or other devices, mount them securely in the corresponding positions.
• Install expansion cards (GPU, sound cards, etc.) into the PCIe slots and secure them with screws. Ensure the card's length fits within the chassis clearance and does not obstruct drive cages or cables.
• Install case fans or radiators to optimize airflow. Connect fans to the motherboard fan headers or a dedicated fan controller. Plan cable routing to avoid obstacles around the motherboard tray and ensure unobstructed airflow paths.
• Manage cables: route power, data, and peripheral cables through the back panel to keep the interior tidy. Close the side panels, attach any accessory panels, and perform a first boot to verify POST, fan behavior, and thermals. Recheck cable connections and power-on indicators, then fine-tune fan speeds if needed.
