6 Best Alternatives to the Iesooy Micro ATX Compact Case (2026)

How the alternatives compare

JOYJOM Compact Micro-ATX Case

The JOYJOM Compact Micro-ATX Case supports standard ATX power supplies instead of the Iesooy’s SFX requirement. This expands your hardware options significantly. It shares the Micro-ATX motherboard support and USB 3.0 connectivity found in the original. However, it lacks the transparent acrylic side panel, offering a more traditional opaque look. The dimensions are slightly wider at 6.3 inches compared to the Iesooy’s 6.69-inch depth, but it remains compact. If you need a standard PSU for easier upgrades or replacements, this model provides that flexibility while keeping the small footprint suitable for desktop use.

Iesooy Micro-ATX Steel Mini Case

This Iesooy Micro-ATX Steel Mini Case uses steel construction rather than the original’s acrylic side panel. It maintains support for both Micro-ATX and ITX motherboards. The width is narrower at 5.7 inches, making it even more space-efficient on your desk. It retains the USB 3.0 front port for convenient connectivity. Unlike the original, it does not explicitly mention SFX PSU support or pre-installed fans. The design prioritizes durability and a smaller physical footprint. If you prefer a solid metal build over clear visibility and need the tightest possible width for your setup, this variant offers a sturdier, more compact alternative without sacrificing core compatibility.

JOYJOM 14.6L Micro ATX Case with RGB Fans

The JOYJOM 14.6L Micro ATX Case with RGB Fans includes pre-installed RGB fans, adding aesthetic value the original lacks. It supports Micro-ATX boards and features Type-C connectivity alongside USB 3.0, offering faster data transfer options. The case volume is 14.6 liters, providing ample space for graphics cards under 310mm. It uses a standard ATX power supply, differing from the Iesooy’s SFX requirement. The dimensions are 10.4 inches wide by 13.8 inches high. If you want modern connectivity like Type-C and visible RGB lighting in a compact Micro-ATX form factor, this model provides enhanced features and standard power supply compatibility.

UTLGAMENG Micro ATX Case with 80mm Fan

The UTLGAMENG Micro ATX Case with 80mm Fan focuses on basic cooling with an included 80mm fan. It supports Micro-ATX and ITX motherboards, similar to the original. However, it lacks the detailed GPU length specifications and SFX PSU support listed for the Iesooy. The design is simpler, prioritizing compatibility over advanced features like transparent panels or extensive cable management spaces. It is a straightforward option for small builds. If you need a no-frills case for ITX or Micro-ATX systems and do not require high-end GPU clearance or specific power supply types, this model offers a compact, functional solution with basic intelligent cooling.

Iesooy Micro ATX Steel Chassis

This Iesooy Micro ATX Steel Chassis is a steel variant of the original brand, offering durability over acrylic visibility. It supports Micro-ATX and ITX motherboards and includes USB 3.0 connectivity on the front panel. Like the original, it is designed for compact builds. However, it does not explicitly list SFX PSU support or GPU length limits in the provided data. The construction is steel, providing a solid feel. If you prefer the Iesooy brand but want a metal chassis instead of acrylic for better rigidity and a different aesthetic, this alternative maintains the compact Micro-ATX focus while changing the material composition.

Cooler Master Q300L Modular Micro-ATX Case

The Cooler Master Q300L Modular Micro-ATX Case features a transparent panel for component visibility, similar to the Iesooy’s aesthetic goals. It supports Micro-ATX motherboards and offers modular I/O for customizable connectivity. The dimensions are 9.06 inches wide by 15 inches high, making it taller and wider than the Iesooy. It weighs only 1.06 pounds, indicating a lighter construction. The case emphasizes airflow and visual display. If you prioritize modular I/O options and a larger internal volume for better airflow in a Micro-ATX build, this Cooler Master model provides a different structural approach while maintaining the compact form factor focus.
