JOYJOM Open Frame Stackable Server Alternatives: 6 Similar Picks Compared

How alternatives compare to JOYJOM

SilverStone 4U Rackmount Server Chassis

The SilverStone 4U Rackmount Server Chassis replaces open-air exposure with a locked, enclosed metal enclosure. It measures 17.6 by 6.93 by 16.9 inches and weighs 23.8 pounds, offering significant mass for stability in a rack environment. While the JOYJOM bench allows flexible horizontal or vertical placement for testing, this SilverStone unit is designed strictly for secure, fixed rack mounting. It supports Micro-ATX boards and prioritizes physical drive access within a protected shell. You should choose this option if you need a secure, high-capacity server solution that protects components from dust and accidental contact, rather than a flexible test bench.

JOYJOM Stackable Open Frame Server Chassis

The JOYJOM Stackable Open Frame Server Chassis shares the same brand DNA but offers a different footprint. It measures 17.1 by 7.68 by 16.9 inches, providing a wider base than the original bench. Both units support Micro-ATX motherboards and are designed for stackable server racks or test benches. However, this model focuses on a larger, more stable horizontal layout for engineers stacking multiple units. It gives up the compact 14.6L volume of the original in favor of a broader platform. Pick this version if your workstation requires a wider base for additional peripheral mounting or if you prefer a larger open frame structure for dense server testing environments.

Pstaroth Open Frame Stackable Test Bench

The Pstaroth Open Frame Stackable Test Bench matches the original JOYJOM unit in volume at 14.6L but differs in physical dimensions. It measures 14.2 by 1.77 by 18.5 inches, resulting in a much flatter, wider profile compared to the original's 13.8-inch height. Both support Micro-ATX motherboards and are built for stackable server racks. The Pstaroth model emphasizes horizontal density and expandability. It offers robust motherboard support similar to the original but sacrifices vertical clearance for a low-profile design. Choose this alternative if you prioritize a low center of gravity and horizontal stacking density over the taller, more traditional bench layout of the original.

Cooler Master N200 Mesh Mini-Tower

The Cooler Master N200 Mesh Mini-Tower shifts from an open frame server bench to a compact, enclosed mini-tower case. It measures 7.9 by 14.9 by 17.5 inches and weighs 9.5 pounds, providing a fully enclosed environment for a Micro-ATX build. Unlike the open-air JOYJOM bench, this case offers better dust protection and acoustic isolation while still supporting liquid cooling. It is designed for users who need a compact, well-ventilated case for standard desktop builds rather than server racks. Select this option if you want a traditional tower form factor with mesh airflow for a Micro-ATX system, rather than an exposed test bench for server applications.

SilverStone Micro-ATX Small Form Factor Case

The SilverStone Micro-ATX Small Form Factor Case offers a compact, enclosed solution for Mini-ITX and Micro-ATX builds. It measures 15 by 13 by 19 inches and weighs 13.5 pounds, providing a sturdy metal enclosure. This case is designed for builders who need to fit large GPUs into a small footprint, offering a practical layout for 2.5-inch storage and standard ATX power supplies. Unlike the open-frame JOYJOM bench, it provides full component protection and a more traditional desktop form factor. Choose this SilverStone model if you require a secure, space-efficient case for a compact desktop build, rather than an open chassis for server testing or stacking.

Chieftec Micro-ATX Case

The Chieftec Micro-ATX Case is another open-air chassis, similar in concept to the JOYJOM bench but sized for Micro-ATX boards. It measures 18.1 by 13 by 15.7 inches and weighs 11.2 pounds. This model offers straightforward component access and prioritizes airflow and easy maintenance over acoustic isolation. It does not support the broader range of motherboard sizes like EATX or ATX found in the original bench. Pick this Chieftec unit if you need a simple, open frame for Micro-ATX builds where easy access is critical, and you do not require the larger motherboard support or stackable server capabilities of the original JOYJOM chassis.
