Who it fits

Okinos Walnut Key Specs Explained

Case Type: Mid-Tower

This size fits standard ATX motherboards while keeping the overall footprint manageable for most desks. You get enough internal space for multiple drives and large graphics cards without taking up too much floor space. It is a practical choice if you want a balanced build that is easy to move or store.

Side Panel: Tempered Glass

The tempered glass side panel allows you to see your internal components clearly. This is useful for showcasing your RGB lighting and cable management. It also provides structural rigidity compared to thin plastic panels. You should handle it with care during installation to avoid scratches or accidental impact damage.

Included Fans: 4x 120mm ARGB PWM

Four pre-installed 120mm fans provide immediate airflow and synchronized lighting effects. The PWM feature allows the motherboard to adjust fan speeds based on temperature, which helps keep your system cool while reducing noise. The ARGB lighting adds visual appeal that you can control via software or the included controller.

Max GPU Length: 410mm

This case supports graphics cards up to 410mm in length, which covers most high-end models including the RTX 4090. You do not need to worry about clearance issues when installing large hardware. This generous space ensures your GPU has room for its own cooling fans and does not touch the case wall.

Radiator Support: 360mm

You can install a 360mm liquid cooling radiator, typically at the top of the case. This allows for efficient heat dissipation from your CPU, keeping temperatures low under heavy loads. It is a key spec for enthusiasts who want to maximize performance with advanced cooling solutions without sacrificing other component space.

Design And Build Quality

The Okinos Walnut ATX Mid-Tower Case blends natural materials with a standard black chassis. The listing describes genuine walnut wood fusion on the exterior, which gives the unit a distinct look for modern workspaces. You get a tempered glass side panel for clear component visibility. The overall dimensions are 17.1 inches in length, 15.4 inches in height, and 11.9 inches in width. The case weighs 14.6 pounds. This weight suggests a sturdy build that can handle heavy internal components without flexing.

The layout prioritizes vertical airflow with dual air intake channels at the bottom and side. The top serves as the main exhaust. This design helps manage heat for high-end GPUs. The case supports graphics cards up to 410mm long. There is a 35mm gap between the pre-installed fans and the GPU to prevent overcrowding. You can install a 360mm radiator at the top and a 240mm radiator on the side. CPU air coolers up to 175mm in height are also supported.

Controls are located on the top I/O panel. According to the listing, this includes a Type-C 3.2 Gen 2 port, two USB 3.0 ports, and audio jacks. You also get power and restart switches, plus buttons for ARGB fan control. The case comes with four magnetic filters and six reusable PCIe slots for maintenance and modding. This finish and layout suit users who want aesthetic appeal without sacrificing cooling performance.

Setup And Daily Use Guide

Setting up this case involves managing the pre-installed cooling and lighting systems. You receive four 120mm ARGB PWM fans, with three reverse-blade units at the bottom and one standard fan at the rear. These connect to an included ARGB controller with four 3-pin connectors. You can sync the lighting effects with your motherboard for unified visuals. The case supports a vertical airflow design with dual intake channels at the bottom and side, while the top serves as the main exhaust. This layout helps direct heat away from your components efficiently.

For daily use, the front I/O panel provides convenient access. It features a Type-C 3.2 Gen 2 port with 10Gbps transfer speeds, two USB 3.0 ports, and audio jacks. You also have dedicated power and restart switches, along with buttons to customize the ARGB lighting directly. The magnetic filters on the intake areas allow you to clean dust without tools, maintaining performance over time. The six reusable PCIe slot covers offer flexibility for cable management and custom builds.

Internally, you have ample space for high-end hardware. The case supports GPUs up to 410mm in length, with a 35mm gap preventing overcrowding. You can install a 360mm radiator at the top and a 240mm unit on the side simultaneously. Air coolers up to 175mm in height also fit comfortably. The tempered glass side panel ensures you can view your components clearly during operation.

Check Compatibility And Upkeep

Before you commit to this chassis, verify your internal components fit the listed limits. The case supports GPUs up to 410mm and CPU coolers under 175mm tall. You must ensure your graphics card does not exceed this length, as the 35mm fan gap is tight for massive cards. Check that your motherboard is ATX, as smaller forms are not supported. You will need to manage the four pre-installed ARGB fans via an included controller or motherboard header, so confirm your board has the correct 5V 3-pin ARGB header. Keep the magnetic dust filters clean regularly to maintain airflow efficiency. This case suits builders who prioritize aesthetics and vertical airflow. It may not fit users with non-standard motherboard sizes or extremely long GPUs. Compare it against other mid-tower options if you need more expansion slots or different cooling configurations. This model is best for those who want a ready-to-use setup with natural wood accents.

Check before you buy

• Verify GPU length is under 410mm for proper fit.
• Confirm CPU cooler height is under 175mm.
• Ensure motherboard is ATX format.
• Check for 5V 3-pin ARGB header on motherboard.
