The best aluminum Mini ITX case depends on the hardware you plan to install and how compact the build needs to be. The JOYJOM is best for a very small build with a limited-size graphics card, while the Lian Li A4-H2O suits buyers who need support for a triple-slot GPU and 240mm liquid cooling. The JONSBO NV10 offers a compact aluminum design that can stand upright or lie flat. Compare the listed dimensions and component limits before choosing.
| Case | Best suited for | Key detail |
|---|---|---|
| JOYJOM Mini ITX | Minimal-volume builds | 4.3L; compact GPU and cooler limits |
| Lian Li A4-H2O | More capable gaming builds | 11L; triple-slot GPU and 240mm AIO support |
| JONSBO NV10 Black | Flexible desktop placement | About 4.5L; vertical or horizontal orientation |
| Yoqanr Open Frame | Open-frame or test-bench setups | Supports ITX and listed 17 × 19 cm boards |
| JONSBO NV10 Silver | Compact builds with a silver finish | About 4.5L; PCIe 4.0 extension cable included |
JOYJOM 4.3L Aluminum Mini ITX Case
This is the best fit for a buyer prioritizing a very small enclosure. Its stated capacity is 4.3 liters, and the body is made from 2.0mm aluminum alloy. The listed exterior dimensions are 7.3 × 4.1 × 8.8 inches.
The case supports a standard 17 × 17 cm Mini ITX motherboard, a FLEX 1U power supply, and a graphics card measuring up to 17 × 10 × 4 cm. It includes an 18.5 cm PCIe 3.0 riser cable and lists room for two 2.5-inch SSDs under 9mm thick.
Best for: Compact builds using components within those size limits. Consider: The maximum listed CPU cooler height is less than 36mm, so check cooler dimensions before buying.
Lian Li A4-H2O Compact SFX Case
The A4-H2O is better for buyers who want a compact case without giving up the listed support for larger performance components. At 11 liters, it is larger than the two JONSBO NV10 options, but its feature list specifies support for a triple-slot graphics card and a 240mm AIO liquid cooler.
Its sandwich layout places the graphics card behind the motherboard and uses a PCIe Gen 5 riser cable. Mesh panels on the top, sides, and bottom provide ventilation. A removable bracket supports SFX and SFX-L power supplies, and the case has a premium aluminum exterior in silver or black.
Best for: A compact gaming or performance system that needs the listed GPU and cooling options. Consider: Confirm the exact component dimensions and power supply format before assembling; the provided details do not specify maximum GPU length.
JONSBO NV10 Black Aluminum Case
The black NV10 is best for buyers who want a small desktop case with flexible placement. It has an approximate 4.5-liter volume and measures 205 × 205 × 108mm. Its aluminum alloy shell has a sandblasted finish and North American walnut trim.
The case can be placed standing or lying down, and the listed package includes a PCIe 4.0 extension cable. A pull handle on the upper cover is designed to make disassembly and maintenance easier. The product information also describes tool-free operation.
Best for: A compact setup where orientation and a distinctive aluminum-and-wood appearance matter. Consider: The provided features do not state maximum graphics card, cooler, or power-supply dimensions, so verify fit before selecting parts.
Yoqanr Mini ITX Open-Frame Test Bench
This open-frame design is best for a buyer who wants an accessible test bench or an exposed component layout rather than a conventional enclosed case. Its listed motherboard support includes ITX 17 × 17 cm and 17 × 19 cm boards. The product details describe a universal hard-drive location for a solid-state or mechanical drive.
The case lists support for a standard large power supply and a replaceable SFX power-supply fixture. The open layout can make components easier to access, but the available product information does not provide a case volume or detailed component clearance limits.
Best for: Test-bench-style setups and buyers who value open access. Consider: Avoid choosing it as a closed, portable system without confirming how exposed components will be protected in your intended location.
JONSBO NV10 Silver Aluminum Case
The silver NV10 provides the same stated compact format as the black version, making it a better choice when a lighter exterior suits the workspace. It has an approximate 4.5-liter capacity, measures 205 × 205 × 108mm, and can be positioned upright or horizontally.
Its aluminum alloy shell has a sandblasted finish with North American walnut trim. The listed PCIe 4.0 extension cable, pull-handle top cover, and tool-free operation are practical details for assembly and access.
Best for: Buyers seeking a small aluminum case in silver with flexible placement. Consider: As with the black model, confirm graphics card, cooler, and power-supply clearances because those limits are not included in the supplied specifications.
Buying Guide: How to Choose an Aluminum Mini ITX Case
How small should the case be?
Compare listed volume and outside dimensions, not just the Mini ITX label. The JOYJOM is the smallest listed option at 4.3 liters, and both NV10 versions are about 4.5 liters. The Lian Li is 11 liters, providing stated support for a triple-slot GPU and a 240mm AIO. Smaller cases can impose stricter component limits.
Will your graphics card and cooler fit?
Check the exact card length, height, and thickness against the case’s supported dimensions. The JOYJOM gives a maximum graphics card size of 17 × 10 × 4 cm and a CPU cooler height below 36mm. For the other enclosed cases, the supplied details do not give all clearances, so confirm specifications for your planned components before ordering.
Which power supply and riser cable matter?
Match the power supply format to the case: the JOYJOM lists a FLEX 1U unit, while the Lian Li supports SFX and SFX-L. The JOYJOM includes a PCIe 3.0 riser, the Lian Li specifies PCIe Gen 5, and both NV10 listings specify PCIe 4.0 extension cables. Check the motherboard and graphics card configuration against the chosen riser.
Do you need an enclosed case or an open frame?
An enclosed case is generally the more appropriate direction for a traditional desktop build. The Yoqanr is explicitly an open-frame design, which offers access but does not provide the same enclosure described by the other cases. Consider where the system will sit and how exposed hardware fits your use.
