Who it fits
Good fit for
You should consider this case if you are building a compact desktop for a small desk or entertainment center. The 7.3L volume and slim 3.62-inch width make it ideal for tight spaces. It suits users who need Micro-ATX or ITX motherboard support but want more expansion options than a standard ITX box. The front I/O with USB 3.0 is convenient for daily use. If you plan to use a low-profile GPU and a small 1U power supply, this case provides the necessary internal clearance for a clean, small-form-factor build.
Who should skip it
You should look elsewhere if you require full-sized ATX motherboards or standard height graphics cards. This case is limited to Micro-ATX, DTX, and ITX boards, so larger components will not fit. The slim 3.62-inch width restricts you to low-profile or half-height GPUs. You cannot install a standard 3.5-inch hard drive; only 2.5-inch SSDs are supported. Additionally, CPU coolers must be under 73mm in height. If you need extensive storage or high-end cooling solutions, this compact design will be too restrictive for your needs.
Verdict: This case is a practical choice for compact Micro-ATX and ITX builds that prioritize space savings. It offers decent connectivity for its size, provided you stick to low-profile components.
Key specs explained for this case
Case Volume: 7.3L
This volume indicates a very compact chassis size. You get a small footprint that fits easily on desks or shelves. It suits users with limited desk space or those building mini PCs. Compare this to standard mid-tower cases which are much larger. The small size helps reduce clutter in tight environments.
Motherboard Support: Micro ATX, DTX, ITX
This case accepts three motherboard form factors. You can use Micro ATX, DTX, or ITX boards. This flexibility allows you to choose the best board for your needs. Smaller boards fit more easily in this tight space. It is ideal for compact builds where you need to save room for other components.
Material: 0.8mm SPCC
The body uses 0.8mm SPCC steel. This is a standard cold-rolled steel alloy. It provides basic structural rigidity for the chassis. The thickness offers decent durability for light use. It is not heavy-gauge steel, so expect a lighter case. This material choice keeps the overall weight down for easier handling.
Front Panel Interface: 2xUSB3.0, 2xUSB2.0
You get four USB ports on the front. Two are USB 3.0 for faster data transfer speeds. Two are USB 2.0 for slower peripherals. This layout gives you easy access to common connections. It is useful for plugging in flash drives or mice. Check your device compatibility for USB 3.0 requirements.
Dimensions: 12.2 inches height
The case stands 12.2 inches tall. This height accommodates vertical or horizontal placement. You can fit it under desks or in tight cabinets. Compare this height to larger towers that need more clearance. The slim profile helps it fit into small spaces without dominating your setup area.
Design and Build Details
The case body is constructed from 0.8mm SPCC steel. This material choice suggests a rigid shell that resists flexing during component installation. The listing specifies this thickness for the main chassis, which helps maintain structural integrity in such a small volume. The exterior finish is black, providing a neutral look that blends with most desk setups. You can place the unit vertically or horizontally, as the design accommodates both orientations. This flexibility allows you to fit the case into tight spaces on shelves or under monitors.
According to the listing, the front panel includes two USB 3.0 ports, two USB 2.0 ports, an HD audio jack, and a power button. These interfaces are positioned for easy access without needing to reach behind the desk. The compact dimensions are 12.2 inches in height, 10.2 inches in length, and 3.62 inches in width. This slim profile means you can slide it into narrow gaps where standard cases would not fit. The small footprint is ideal for users who prioritize desk space efficiency.
The internal layout is constrained by the 7.3L volume. You must select components that fit within these tight limits. The case supports half-height graphics cards without hard drives installed. It also accommodates up to two 2.5-inch SSDs or one 3.5-inch SSD. CPU coolers must be between 63mm and 73mm in height, depending on SSD placement. These restrictions define the build path for this specific chassis.
Setup and Daily Use Guide
Setting up this compact chassis requires careful planning due to its 7.3L volume. You must verify that your components fit within the strict internal dimensions. The case supports Micro-ATX, DTX, and ITX motherboards, giving you flexibility in board selection. However, the 0.8mm SPCC steel body leaves little room for error during installation. You will need to choose a FLEX-Small 1U power supply measuring 15x4x8cm. Standard ATX or SFX units will not fit. Graphics card selection is also limited. You can only install half-height cards if you include a hard drive. If you skip the HDD, you might accommodate slightly larger cards, but the listing notes this depends on specific SSD placement. CPU coolers must be between 63mm and 73mm in height. This constraint ensures the cooler does not interfere with the top panel or side I/O. Daily use is straightforward once built. The front panel provides two USB 3.0 ports, two USB 2.0 ports, HD audio jacks, and a power button. These interfaces allow you to connect peripherals and audio devices directly. The case allows both vertical and horizontal placement. You can position it to suit your desk layout. The compact size makes it easy to move or store when not in use. Just remember to include all necessary screws, as they are packed with the unit.
Before You Buy This Case
Owning this 7.3L chassis requires precise component selection. You must verify that your power supply fits the FLEX-Small 1U form factor, measuring no larger than 15 by 4 by 8 cm. Standard ATX units will not fit. Graphics cards must be half-height and lack attached hard drives. CPU coolers are limited to 63-73mm in height, depending on your SSD configuration. You need to check that your storage matches the supported 2x 2.5-inch or 1x 3.5-inch SSD limit. This case suits users with strict space constraints who prioritize a small footprint over expandability. It stands apart from larger mid-towers by demanding compact parts. You should also note the front panel offers two USB 3.0 and two USB 2.0 ports, along with HD audio. Regular dust cleaning is advised due to the tight internal volume. Ensure your motherboard is Micro-ATX, DTX, or ITX. This guide helps you avoid compatibility issues before purchasing.
Check before you buy
- Confirm your PSU is FLEX-Small 1U size.
- Check GPU is half-height without HDD.
- Verify CPU cooler height is under 73mm.
- Ensure motherboard is Micro-ATX, DTX, or ITX.
