JOYJOM Case vs Open Frame Bench
Motherboard Support
Product A, the JOYJOM Compact Micro-ATX Case, is designed specifically for Micro ATX motherboards with a maximum size of 25.5x25.5cm. It also supports smaller ITX boards measuring 17x17cm. Product B, the JOYJOM Open Frame Stackable Server Bench, offers broader compatibility. It supports motherboards up to 330x330mm, covering EATX, ATX, Micro ATX, and ITX formats. If you need to use larger enterprise or enthusiast motherboards, Product B is the only option that accommodates those form factors. Product A is strictly limited to smaller boards.
GPU Clearance
Graphics card length is a critical factor for many builds. Product A supports a maximum GPU length of 250mm. This limit drops to 225mm if you install 120x120x25mm fans on the front side. Product B provides significantly more room. It supports GPUs up to 310mm with internal fans mounted. If you mount fans externally, Product B allows cards up to 335mm in length. This extra clearance makes Product B suitable for high-end graphics cards that often exceed 300mm, whereas Product A restricts you to shorter models.
Radiator Support
Cooling options differ greatly between these two cases. Product A supports up to two 120mm fans on the front and one 80mm fan on the back. It does not list support for liquid cooling radiators. Product B is built for advanced cooling. It supports up to eight 120mm fans. For liquid cooling, it accommodates a single 360mm radiator, two 240mm radiators, or one 120mm radiator. If you plan to use a large AIO cooler or custom loop with a 360mm radiator, Product B is the clear choice. Product A lacks this capability.
Front Panel Connectivity
Access to ports on the front panel affects daily usability. Product A includes a front panel with one USB 3.0 port, one USB 2.0 port, audio jacks, a power button, and a reset button. This provides convenient access for peripherals and controls. Product B, the open frame bench, does not list any integrated front panel I/O or buttons in its specifications. You would need to connect peripherals directly to the motherboard or use extension cables for the power switch. Product A offers better built-in connectivity.
Build and Rigidity
The construction materials impact stability and durability. Product A uses 0.8mm SPCC steel for the body, featuring many air vents for heat dissipation. It weighs 4.85 pounds. Product B uses thicker materials, with 1.5mm SPCC panels and a 0.8mm base plate. It also has a sandblasted finish for added protection. Product B is designed for stacking up to 10 units horizontally, indicating a focus on structural integrity for rack environments. Product A is a standalone compact case. Product B offers superior rigidity and professional build quality.
