Who it fits
Good fit for
This case suits users building lightweight, space-saving desktops or HTPCs. It is ideal for those using integrated graphics motherboards who need a compact footprint. You will appreciate the external power adapter for reducing internal clutter and heat. The support for multiple COM ports makes it a practical choice for connecting older peripherals like printers or scanners. It is also a solid option for low-cost DIY projects where portability and minimal size are priorities.
Who should skip it
You should look at another option if you plan to use a discrete graphics card. This chassis does not fit ATX power supplies or standard discrete GPUs. The CPU cooler height limit is strict, ranging from 30mm to 58mm depending on storage installation. If you require extensive internal storage beyond one 3.5-inch drive or two 2.5-inch drives, this case will not meet your needs. It is not suitable for high-performance gaming rigs.
Verdict: This is a practical, compact case for specific Mini ITX builds that prioritize size over expandability. It works well for integrated graphics systems and legacy peripheral connections.
Key specs for this mini case
Case Volume: 3.5L
This tiny volume makes the chassis highly portable and space-saving. You can easily place it on a small desk or mount it behind your monitor. The compact footprint is ideal for users with limited workspace who want a full desktop build without the bulk of a standard tower. It fits well in tight environments where larger cases simply will not fit.
Motherboard Support: Mini ITX, DTX
You must use a Mini ITX or DTX motherboard, which are smaller than standard ATX boards. These boards often feature integrated graphics, which is necessary since this case cannot fit a discrete graphics card. This setup is best for office PCs, home theater systems, or light gaming builds where high-end expansion slots are not required for your workflow.
Build Material: 0.8mm SPCC
The steel thickness is 0.8mm, which is thicker than the common 0.4mm or 0.6mm alternatives found in many budget cases. This added material provides better resistance to scratches and physical impacts. You will notice a more robust feel when handling the chassis. It reduces flex during component installation and offers a sturdier structure for your internal hardware components.
Power Supply Support: PICO PSU + Adapter
This case requires a PICO-PSU board paired with an external 12V power adapter. Standard ATX power supplies do not fit inside. Using an external adapter moves heat and clutter out of the chassis, improving airflow. You must ensure the adapter wattage covers the total power draw of your motherboard and storage drives, as there is no room for a high-wattage internal unit.
Build Quality and Layout Details
The chassis is constructed from 0.8mm SPCC steel, which the listing notes is more substantial than thinner 0.4mm or 0.6mm alternatives. This thickness offers better resistance to scratches and impacts. The exterior finish is a simple black color. The total weight is 2.2 pounds, making the unit lightweight and easy to reposition. According to the listing, the compact 3.5L volume measures 21.6 by 22.7 by 7.2 centimeters. This small footprint allows you to place the case on a small desk or mount it behind your screen. The design prioritizes space-saving and portability for users with limited workspace.
Internal layout choices are driven by the Mini ITX and DTX motherboard support. You can install one 3.5-inch HDD or two 2.5-inch SSDs on the top panel. An additional 2.5-inch SSD fits on the front panel. The listing also mentions support for six COM ports, useful for connecting older equipment like printers or scanners. CPU cooler height limits vary based on top storage. With no drive installed, the limit is 58mm. Adding a 7mm drive reduces this to 50mm, while a 25mm drive drops it to 30mm.
Front I/O includes two USB 2.0 ports and HD audio connectors. Power is handled via an external PICO PSU adapter, which reduces internal heat and clutter. The case does not fit discrete graphics cards or standard ATX power supplies. You must ensure your power supply wattage accounts for all hardware components. This external approach keeps the interior clean but requires managing the adapter outside the chassis.
Setup and Everyday Use Guide
Setting up this compact chassis requires careful planning due to its strict size limits. You must use a Mini ITX or DTX motherboard, preferably one with integrated graphics. The case does not support discrete graphics cards or standard ATX power supplies. Instead, you need a PICO-PSU board paired with a 12V external adapter. This external power setup helps reduce internal heat and clutter, which is critical in such a small volume. When installing components, you must account for the power supply wattage relative to your total hardware consumption. Storage options are limited but functional. You can mount one 3.5-inch HDD or one 2.5-inch SSD on the top panel, and add a second 2.5-inch SSD to the front. However, installing a 3.5-inch drive reduces the allowed CPU cooler height to just 30mm. Without a top drive, you gain 58mm of clearance, or 50mm with a thin 7mm drive. For connectivity, the front I/O provides two USB 2.0 ports and HD audio jacks. The rear panel supports six COM ports, allowing you to connect legacy devices like printers or scanners. This case is ideal for users who need a lightweight, portable desktop that mounts behind a screen. It suits low-cost DIY projects where space is at a premium and modern discrete GPUs are not required.
Before You Buy This Mini Case
You need to verify your power supply type first. This chassis requires a PICO PSU with a 12V external adapter. Standard ATX units will not fit. You must also check CPU cooler height carefully. Without a top hard drive, the limit is 58mm. Adding a 7mm SSD drops this to 50mm. A 25mm drive reduces it further to 30mm. Integrated graphics are strongly recommended since no discrete GPU fits. You should plan your cable management around the limited front I/O ports, which include only two USB 2.0 connections and HD audio. Keep the interior clean to maintain airflow in such a small volume. This case suits users who prioritize space savings over expandability. It fits well alongside larger SFF options if you need a lightweight, portable build. Ensure your storage needs align with the single 3.5" HDD or two 2.5" SSD slots available.
Check before you buy
- Confirm you have a PICO PSU and 12V adapter.
- Check CPU cooler height against drive installation plans.
- Verify motherboard has integrated graphics for compatibility.
- Ensure you need only two USB 2.0 ports.
