Key specs explained for this case
Motherboard Support: Micro-ATX, ITX
You can install either Micro-ATX or ITX motherboards in this chassis. This flexibility allows you to choose a board that fits your performance needs without being locked into one size. ITX boards save space, while Micro-ATX offers more expansion slots. Check your motherboard dimensions carefully to ensure it fits within the case limits before purchasing.
Max GPU Length: 280mm
The graphics card you choose must not exceed 280 millimeters in length. Most mid-range cards fit within this limit, but high-end models often run longer. Measure your current or intended GPU to verify compatibility. If your card is longer, you will not be able to close the side panel or may block other components inside the case.
Material: 0.8mm-thick steel plate
The chassis body uses steel that is 0.8 millimeters thick. This thickness provides a rigid structure that resists bending during transport or installation. It also helps with heat dissipation through the numerous ventilation holes. Thinner steel can feel flimsy, so this gauge offers a solid feel for a budget-friendly mini case.
CPU Cooler Height: 120mm
Your CPU cooler must be 120 millimeters tall or shorter. This limit restricts you to low-profile air coolers or small tower designs. Large air coolers will not fit. If you need better cooling performance, you may need to consider an all-in-one liquid cooler, provided it fits the available space and radiator mounting options.
Storage: HDD*2 + SSD*2
You can install up to two hard drives and two solid-state drives. This setup allows you to combine high-capacity storage with fast boot drives. Verify the mounting brackets and cable management space before buying. This configuration is suitable for users who need ample storage for games and files without requiring a full-sized tower case.
Steel Build and Compact Layout
The chassis body is constructed from 0.8mm-thick steel plate, according to the listing. This material choice provides structural rigidity for a compact enclosure. The exterior features numerous ventilation holes designed to aid heat dissipation. You do not need additional fans for basic airflow, though the steel construction ensures the case remains sturdy during transport and installation. The finish is a simple black, which keeps the visual profile clean and unobtrusive in most setups.
External dimensions are 11.4 x 5.7 x 13 inches, with a weight of 6.15 pounds. This footprint allows the case to fit on smaller desks or in tight spaces. The weight suggests a solid build that will not tip easily, yet it remains light enough to move if you need to reposition your workstation. The compact size is ideal for users who prioritize space efficiency over massive expansion slots.
The front panel includes one USB 2.0 port, one USB 3.0 port, an audio jack, a power button, and an indicator light. These controls are positioned for easy access without reaching behind the desk. The layout is straightforward, focusing on essential connectivity. You get standard inputs for peripherals and audio, which covers most daily computing tasks. The design avoids unnecessary complexity, delivering a functional interface that supports quick interactions.
Setup and everyday use guide
Installing components in this chassis requires careful planning due to its compact dimensions. You must verify that your motherboard fits within the specified Micro-ATX or ITX footprint. Graphics cards must not exceed 280 mm in length. CPU coolers are limited to a maximum height of 120 mm. Power supply selection is strict; only standard Micro ATX (SFX) units measuring 4.9 by 3.9 by 2.5 inches are supported. Standard ATX power supplies will not fit, so you must check your PSU dimensions before assembly. Storage options allow for two hard drives and two solid-state drives. The chassis is constructed from 0.8mm-thick steel, which provides a rigid frame for your components. The exterior features numerous ventilation holes to aid passive and active heat dissipation. You do not need to install additional fans immediately, as the design promotes airflow through its structure. Front panel connectivity includes one USB 2.0 port, one USB 3.0 port, an audio jack, a power button, and an indicator light. These ports offer convenient access for peripherals without reaching behind the desk. The unit weighs 6.15 pounds and measures 11.4 by 5.7 by 13 inches. This size allows it to fit on most desks or shelves. The package includes only the case itself, with no other accessories. You will need to source your own mounting screws and fans if required. The black finish blends easily with most desktop environments. Daily use involves plugging peripherals into the front USB 3.0 and audio ports for quick access. The steel construction ensures the case remains stable during operation. Ensure all components are securely fastened to prevent vibration. The ventilation holes help maintain temperatures during typical workloads.
Before you buy this case
You need to verify component compatibility before ordering. The chassis supports only Micro-ATX and ITX motherboards. It does not accept standard ATX power supplies. You must use a standard Micro ATX or SFX power supply. Check your graphics card length carefully. The maximum limit is 280 mm. CPU coolers cannot exceed 120 mm in height. This case includes no fans. You will need to purchase case fans separately to ensure proper airflow. The steel construction offers rigidity, but the ventilation holes are fixed. You cannot add more intake points. Upkeep is simple. Wipe the exterior with a dry cloth. Dust may accumulate in the holes. Regular cleaning helps maintain temperatures. This option suits users with small form factor builds who prioritize steel durability over pre-installed cooling. It fits alongside other compact cases by offering a specific, limited footprint for ITX and Micro-ATX systems.
Check before you buy
- Confirm your motherboard is Micro-ATX or ITX size.
- Ensure your GPU is under 280 mm long.
- Check that your CPU cooler is under 120 mm tall.
- Verify you have an SFX or standard Micro ATX PSU.
