6 Best Alternatives to the JOYJOM Open Air ATX Test (2026)

How these cases differ from JOYJOM

Cooler Master N200 Mesh Mini-Tower

The Cooler Master N200 Mesh replaces the open frame with a fully enclosed Mini-Tower design. It measures 17.5 inches long and 14.9 inches high, offering significantly more space than the JOYJOM’s compact 10.4-inch width. You get a dedicated mesh front for improved airflow while maintaining a standard ATX power supply bay. The 9.5-pound weight indicates sturdier construction compared to the lightweight 2.54-pound JOYJOM frame. This case suits you if you need a complete enclosure to reduce dust and noise, rather than the bare-bones accessibility of an open test bench. It sacrifices the minimal footprint for better component protection and cable management options.

SilverStone Micro-ATX Small Form Factor Case

The SilverStone SG11 is a Small Form Factor case designed for dense Micro-ATX builds. It measures 19 inches long and 13 inches high, providing a rigid structure for long graphics cards and multiple 2.5-inch drives. Unlike the JOYJOM’s open frame, this unit offers a fully enclosed environment that protects components while maintaining a compact footprint. The 13.5-pound weight reflects its robust metal construction. You should choose this if you need a high-density layout for storage and GPU length in a small area. It gives up the easy visual inspection of the JOYJOM but provides superior structural integrity and a more traditional, protected build environment for serious Micro-ATX enthusiasts.

Chieftec Micro-ATX Case

The Chieftec CI-01B-OP is a Micro-ATX case focused on drive expansion. It measures 18.1 inches long and 13 inches high, offering a traditional tower shape. This case includes ample drive bay space, which the JOYJOM lacks aside from a single slot. The 11.2-pound weight suggests a solid steel chassis. You should pick this if you require multiple storage drives and standard connectivity without the openness of a test bench. It sacrifices the minimal size and easy access of the JOYJOM for a more conventional build experience. This option is ideal for users who prioritize storage capacity and a fully enclosed system over the bare-metal aesthetic of an open frame.

Cooler Master Q300L Modular Micro-ATX Case

The Cooler Master Q300L is a modular Micro-ATX case with a transparent side panel. It measures 15.4 inches long and 15 inches high, offering flexible I/O placement options. The 1.06-pound weight makes it exceptionally light, even lighter than the JOYJOM frame. You should choose this if you want a compact build with visual transparency and modular flexibility. It provides a complete enclosure with a glass panel, unlike the open JOYJOM. This case is best for builders who value airflow and compact dimensions but still want the aesthetic appeal of visible internals. It trades the raw accessibility of the test bench for a more polished, customizable enclosure experience.

Thermaltake Versa H18 Tempered Glass Micro-ATX Case

The Thermaltake Versa H18 features a tempered glass side panel for a Micro-ATX build. It measures 15.4 inches long and 15 inches high, providing a small footprint with visible internals. The 10.2-pound weight indicates a sturdy build. You should select this if you want a compact case with a modern aesthetic and glass visibility. It offers a fully enclosed environment, contrasting with the open JOYJOM frame. This case is suitable for users who prioritize a small size and visible components over maximum expansion. It gives up the bare-metal access of the test bench but delivers a polished look with tempered glass, ideal for gaming setups where aesthetics matter.

iTek QBO 8 Evo Micro-ATX Cube Case

The iTek QBO 8 Evo is a Micro-ATX cube case with integrated ARGB lighting. It measures 14.2 inches long and 13.1 inches high, featuring a unique cube shape. The 6.61-pound weight suggests a solid build. You should choose this if you want immediate ARGB lighting and a distinctive form factor. It supports 120mm fans and provides a fully enclosed environment, unlike the open JOYJOM. This case is ideal for small desks and users who prioritize visual appeal with lighting effects. It sacrifices the minimal footprint and easy access of the test bench for a more stylized, enclosed build. It is best for those who want a compact system with modern lighting features without the openness of a frame.
