Micro ATX Case MATX DTX ITX Mini PC Case - Compact 7.3L Design

In this review of the Micro ATX Case from JOYJOM the bottom line is simple: this is a compact, rigid enclosure for builders who need a tiny desktop footprint without sacrificing basic expandability. The case is only 7.3L and accepts both Micro ATX and ITX motherboards, which makes it ideal for a small home office, HTPC, or space-conscious workstation. Its strongest selling point is a sturdy SPCC body and good airflow in a tiny package, while some buyers should note the limited internal room for cooling or long drives.

Key Features

• Ultra-compact 7.3L body: The very small internal volume keeps a desktop or media shelf tidy and lets the case be used vertically or horizontally.
• Dual motherboard compatibility: Supports Micro ATX (24.4 x 24.4 cm) and ITX (17 x 17 cm) boards so builders can choose more I/O or a minimal layout.
• Flexible power supply fit: Accepts a FLEX-Small 1U style PSU (15 x 4 x 8 cm) to enable compact, efficient builds without a conventional ATX supply.
• Front I/O convenience: Two USB 3.0 ports, two USB 2.0 ports and HD audio on the front panel give immediate access for peripherals and headsets.
• Solid SPCC construction: The 0.8 mm SPCC body feels sturdy and reduces chassis flex compared with thinner sheet metal cases.
• Minimal storage options: Space for either 2x 2.5 in SSDs or 1x 3.5 in drive keeps the drive list simple and suited to SSD-first builds.

Who It's For

This case is aimed at hobbyists and small-form-factor builders who need a truly compact chassis that can hold a Micro ATX board or an ITX board while keeping a low profile on a desk or AV shelf. It is a good choice for users who prioritize build quality, front panel connectivity and basic ventilation over advanced cooling or many internal drives.

People who need long, full-height graphics cards, multiple 3.5 in drives, or large air coolers should look elsewhere; the case supports only half-height graphics and CPU coolers in the 63 mm to 73 mm range depending on storage placement, and fan mounting options are limited compared with larger enclosures.

Pros & Cons

Pros

• Sturdy 0.8 mm SPCC construction gives a solid feel and resists flex during assembly.
• Very compact 7.3L footprint that can be oriented vertically or horizontally for flexible placement.
• Good front I/O with 2x USB 3.0 and 2x USB 2.0 plus HD audio makes daily use convenient.
• Simple internal layout that suits SSD-first builds and small power supplies.

Cons

• Limited cooling and fan mounting options reported by some users, which may restrict higher-power builds.
• Storage expansion is modest - only 2x 2.5 in or 1x 3.5 in drive capacity.
