Who it fits
Good fit for
You should choose this chassis if you need a stackable solution for server racks or workstations. The open frame design suits users who prioritize maximum airflow for air or water cooling setups. It fits those who frequently swap motherboards or GPUs during testing. The included tools and power switch make it practical for lab environments where quick access and multiple units are necessary for parallel operations.
Who should skip it
You should look at another option if you need a fully enclosed case for dust protection or noise reduction. This open frame chassis offers no side panels or front mesh. It is not suitable for users who want a clean desktop aesthetic or need to hide cables. If you require extensive drive bays beyond the two HDD and three SSD slots, this unit lacks the storage expansion options found in traditional tower cases.
Verdict: The JOYJOM Stackable Open Frame Server Chassis is a practical, spec-focused tool for testing and server deployment. Its stackable design and robust steel construction make it ideal for professional environments.
Key specs explained for you
Motherboard Support: EATX, ATX, Micro ATX, ITX
This chassis accepts four standard motherboard form factors, from the compact ITX to the large EATX. You can choose any board size within that range. This flexibility is useful if you plan to upgrade your system later. It ensures the case fits most modern workstations. You do not need to check compatibility before buying your main component. The open frame design makes installation easier for all these sizes.
Max GPU Length: 310mm internal, 335mm external
You can install graphics cards up to 335mm long if fans are mounted outside the case. With internal fans, the limit is 310mm. This allows for most high-end consumer cards. You should measure your specific GPU before purchasing. This spec helps you avoid clearance issues. It is important for users building powerful gaming or workstation rigs. The external option gives you slightly more room for bulky cards.
Radiator Support: 360mm
The case supports liquid cooling radiators up to 360mm in size. This allows for effective heat dissipation from high-performance CPUs. You can mount larger radiators than many closed cases offer. This is ideal for overclocking or heavy workloads. The open frame design helps airflow around the radiator. You get better cooling efficiency compared to confined spaces. This spec is key for users prioritizing thermal performance in their build.
Dimensions: 435 x 340 x 195mm
The chassis measures 17.13 by 13.39 by 7.68 inches. This footprint is compact for an open frame. It fits well on desks or in server racks. You can stack up to ten units horizontally. This saves floor space in multi-server setups. The height is low, which may limit some large air coolers. You should verify your cooler height against the 165mm limit. The size is practical for tight workspaces.
Material: 1.5mm SPCC panels
The panels are made from 1.5mm thick SPCC steel. This provides structural rigidity and reduces vibration. The base plate is 0.8mm thick. The sandblasted surface adds protection against scratches. This build quality ensures the case stays stable during operation. You get a durable frame for heavy components. The thickness prevents flexing when installing heavy motherboards or GPUs. It is a solid choice for long-term use.
Build Materials and Stackable Design
According to the listing, the chassis uses 1.5mm thick SPCC steel for all panels and mounting brackets. The base plate is 0.8mm SPCC. This combination provides structural rigidity for an open-frame design. The surface features a sandblasted treatment for added protection. The overall dimensions are 435 by 340 by 195mm. You can place the unit horizontally or vertically. The design allows stacking up to ten units in horizontal mode. This feature makes it suitable for workstation or server rack environments where space is limited.
The layout prioritizes accessibility and cooling. You can install up to eight 120mm fans for air cooling. For liquid cooling, the chassis supports a 360mm radiator, two 240mm radiators, or one 120mm radiator. The maximum CPU cooler height is 165mm. Graphics card support reaches 310mm with internal fans or 335mm with external mounting. Storage options include two HDD bays and three SSD slots. The power supply accommodates ATX units up to 300mm in length.
Controls are minimal but functional. The package includes a power switch for easy operation. You also receive a motherboard spacer wrench and screws for assembly. This setup is ideal for DIY builders who need a durable, stackable chassis for testing or server deployment. The open frame allows for maximum airflow and easy component access.
Setup and Daily Use Guide
Setting up this chassis begins with unpacking the included hardware. The package provides the main frame, a power switch, a motherboard spacer wrench, and necessary screws. You will assemble the unit by attaching the panels and mounting your components. The open-frame design allows you to place the case horizontally or vertically. If you need more units, the listing states it can stack up to ten units in horizontal mode. This feature suits server rack environments or workstations where space efficiency matters.
For daily use, you will connect your power supply and motherboard. The case supports ATX power supplies up to 300mm in length. You can install up to eight 120mm fans for air cooling or fit a 360mm radiator with additional 240mm and 120mm options. Ensure your CPU cooler does not exceed 165mm in height. Graphics cards up to 310mm fit with internal fans, or 335mm if mounted externally. Storage options include two hard drives and three solid-state drives.
The 1.5mm thick SPCC panels provide rigidity during operation. The sandblasted surface offers protection against wear. You can access components easily for maintenance or upgrades. The included power switch simplifies startup. This setup is practical for users who need frequent access to internal hardware. The stackable nature helps organize multiple systems. It is a functional choice for technical tasks requiring an open-air environment.
Before You Buy This Chassis
This open frame case lacks built-in airflow control. You must source your own cooling solution. The listing supports up to eight 120mm fans or multiple radiator configurations. Verify your GPU length against the 310mm internal limit. External mounting extends this to 335mm. Check your power supply length, as it must fit within 300mm. Storage is limited to two hard drives and three solid-state drives. You may need additional cables or mounts for larger components. This chassis suits users who prioritize accessibility and stackability. It fits well in server racks or workstations. Unlike enclosed cases, it exposes all components. This design aids troubleshooting and heat dissipation. Consider your workspace environment. Dust exposure is higher without filters. Regular cleaning will be necessary. This option complements other cases by offering a modular, stackable alternative for specialized builds.
Check before you buy
- Verify GPU length fits 310mm internal or 335mm external limit
- Confirm power supply length is under 300mm
- Check motherboard form factor matches EATX, ATX, Micro ATX, or ITX
- Plan for eight 120mm fans or compatible radiators
- Ensure workspace allows for stackable horizontal placement
