Which one should you choose?
Choose JOYJOM 4.3L Aluminum Mini-ITX Case if
- You need the smallest possible footprint at 4.3L.
- You are building a strict Mini-ITX system.
- You prefer an aluminum alloy body for heat dissipation.
Choose SilverStone Micro-ATX Small Form Factor Case if
- You want to use a Micro-ATX motherboard.
- You require support for graphics cards of any length.
- You prefer using a standard ATX power supply.
Verdict: Choose the JOYJOM if your priority is minimizing space and you are committed to Mini-ITX components. Select the SilverStone if you need flexibility for Micro-ATX boards or long graphics cards. The latter offers more upgrade potential despite its larger size.
JOYJOM vs SilverStone SFF Comparison
Motherboard Support
The JOYJOM case supports only standard Mini-ITX motherboards, which measure 17x17 cm. This limits you to the smallest board size. The SilverStone SG11 offers broader compatibility. It accepts Mini-ITX, Mini-DTX, and Micro-ATX motherboards. If you plan to use a Micro-ATX board for extra expansion slots, the JOYJOM will not work. The SilverStone handles these larger formats without issue. This makes the SilverStone the more flexible choice for builders who want options beyond the strict Mini-ITX standard.
Case Volume
Size is the main difference between these two cases. The JOYJOM is an ultra-compact unit with a volume of just 4.3 liters. Its dimensions are roughly 18.4x10.4x22.3 cm. This tiny footprint is ideal for tight spaces. The SilverStone SG11 is significantly larger, measuring 19x15x13 inches. It weighs 13.5 pounds compared to the JOYJOM's 2.51 pounds. If your priority is minimizing desk or shelf space, the JOYJOM is the clear winner. The SilverStone requires more room and is better suited for standard desks.
GPU Compatibility
Graphics card support differs greatly. The JOYJOM restricts GPUs to a maximum length of 17 cm and a thickness under 4 cm. You must use the included PCIe 3.0 riser cable, which is 18.5 cm long. The SilverStone supports graphics cards of any length. This allows you to install full-size desktop GPUs without restriction. If you need high-end performance cards that are long, the JOYJOM is not viable. The SilverStone provides the freedom to choose any standard desktop graphics card.
Cooling Clearance
Thermal clearance is tight in the JOYJOM. CPU coolers must be less than 36 mm in height. This limits you to very low-profile air coolers or specialized small fans. The SilverStone allows for CPU coolers up to 82 mm in height. This opens up many more aftermarket cooling options for better heat dissipation. If you plan to run a CPU under load, the SilverStone provides much better thermal headroom. The JOYJOM is suitable only for low-power components with minimal cooling needs.
Power Supply Type
The power supply requirements are distinct. The JOYJOM requires a Flex-Small 1U power supply, measuring 15x4x8 cm. These are often used in servers or thin clients. The SilverStone is compatible with standard ATX power supplies. ATX PSUs are widely available and easier to find. Using a standard ATX unit in the SilverStone simplifies upgrades and replacements. The JOYJOM forces you to source a specific, less common form factor for your power needs.
Choose Your Compact Build
Ultra-compact desktop builders
You need the smallest possible footprint. This JOYJOM case offers a 4.3L volume with 2.0mm aluminum alloy construction. It supports Mini-ITX boards and includes a PCIe 3.0 riser cable. The compact 18.4x10.4x22.3 cm dimensions make it ideal for tight spaces, provided your components fit the strict size limits.
Flexible component builders
You want to mix and match parts. The SilverStone SG11 supports Micro-ATX, Mini-DTX, and Mini-ITX motherboards. It accepts standard ATX power supplies and graphics cards of any length. With 82mm CPU cooler clearance and ample 2.5-inch drive space, it offers significantly more internal flexibility than the ultra-small JOYJOM option.
Standard ATX power users
You prefer using standard ATX power supplies instead of small Flex-ATX units. The SilverStone case is compatible with these larger, more common PSUs. This compatibility simplifies your build process and gives you access to a wider range of power options, making it a more practical choice for general small form factor builds.

Frequently asked questions
Is the JOYJOM case smaller than the SilverStone SG11B?
Yes, the JOYJOM 4.3L is significantly more compact. It measures 4.09 by 8.78 by 7.24 inches and weighs 2.51 pounds. The SilverStone SG11B is much larger, with dimensions of 15 by 13 by 19 inches. It also weighs 13.5 pounds. The JOYJOM is designed for extreme portability, while the SilverStone prioritizes internal space for larger components.
Can I install a Micro-ATX motherboard in the JOYJOM case?
No, the JOYJOM 4.3L case only supports Mini-ITX motherboards. It is built strictly for the smallest standard board size. If you need to use a Micro-ATX motherboard, you must choose the SilverStone SG11B instead. The SilverStone unit is explicitly designed to accommodate Micro-ATX boards, offering greater flexibility for component selection.
Does the SilverStone case fit long graphics cards?
Yes, the SilverStone SG11B is designed to support long graphics cards. Its larger internal volume allows for better GPU compatibility compared to ultra-compact options. The JOYJOM case is limited to low-profile parts due to its tiny 4.3L footprint. If you require a standard or large GPU, the SilverStone is the practical choice.
Which case is better for gaming builds?
The JOYJOM case is explicitly categorized for gaming use. However, its suitability depends on your component constraints. It fits Mini-ITX systems with low-profile parts. The SilverStone SG11B supports Micro-ATX and long GPUs. If your gaming build relies on high-performance, full-sized components, the SilverStone provides the necessary space. The JOYJOM suits compact gaming rigs.
What is the weight difference between the two cases?
The JOYJOM case weighs 2.51 pounds, making it very light. The SilverStone SG11B weighs 13.5 pounds. This substantial difference reflects the materials and internal structure. The JOYJOM uses aluminum for a lightweight, portable design. The SilverStone offers a sturdier, larger chassis. You should choose based on whether portability or structural rigidity matters more to you.
Is the JOYJOM case made of aluminum?
Yes, the JOYJOM 4.3L case is constructed from aluminum. The product data specifies it as an aluminum Mini-ITX case. This material choice contributes to its lightweight nature at 2.51 pounds. The SilverStone SG11B is also available in black, but its construction is not specified as aluminum in the provided data. The JOYJOM offers a distinct metallic build for its size.
Can I use an ATX power supply in the SilverStone case?
Yes, the SilverStone SG11B supports ATX power supplies. This is a key advantage for builders who want to use standard, high-wattage PSUs in a small form factor. The JOYJOM case is too small for ATX units and requires low-profile components. If you plan to use a standard ATX power supply, the SilverStone is the only compatible option here.
