Despite their compact size, modern Mini ITX cases offer impressive expandability, cooling options, and connectivity—making them a favorite among PC enthusiasts and professionals alike.

Key Specifications of Mini ITX Cases

Motherboard Compatibility

The Mini ITX case is specifically designed to accommodate Mini ITX motherboards, which measure exactly 6.7 x 6.7 inches (170 x 170 mm). While the case itself is slightly larger to allow for internal components, cable routing, and structural support, it remains significantly smaller than mid-tower or full-tower alternatives.

Despite the compact footprint, Mini ITX motherboards typically support a full-sized CPU socket, two RAM slots, one PCIe x16 slot for a graphics card, and essential I/O connections. This balance of size and capability makes them ideal for building powerful yet compact systems, from gaming rigs to compact office PCs.

CPU Cooler and GPU Support

Due to space constraints, Mini ITX cases impose strict limits on CPU cooler height and GPU length. Most models support CPU air coolers up to 150mm in height, though some ultra-compact designs may restrict this further. Tower-style coolers are often incompatible, so low-profile or compact air coolers—and increasingly, compact AIO liquid coolers—are recommended.

On the GPU front, many modern Mini ITX cases surprisingly support full-length graphics cards exceeding 300mm (over 12 inches), thanks to optimized internal layouts and vertical GPU mounting options. Always verify compatibility with your specific model, as dimensions can vary significantly between manufacturers and chassis designs.

Storage Options

Storage capacity in a Mini ITX case is carefully optimized to maximize space efficiency. Most models support at least one 3.5-inch hard drive (HDD) and multiple 2.5-inch solid-state drives (SSDs), allowing users to balance high-capacity storage with fast boot and load times.

Modern cases increasingly prioritize M.2 NVMe SSDs, which require no cables or drive bays and are mounted directly onto the motherboard or via dedicated M.2 trays inside the case. Some high-end SFF cases even include tool-free mounting systems and hidden storage compartments to maintain a clean internal layout while maximizing expandability.

Port Availability and Front I/O

User convenience is a major focus in Mini ITX design. To simplify peripheral access, most cases feature a well-equipped front or top I/O panel with a range of modern ports. Common configurations include USB 3.0/3.2 Type-A, USB-C (often with 10Gbps or higher speeds), audio jacks, HDMI, and sometimes even power delivery (PD) charging ports.

This front-facing accessibility eliminates the need to reach behind the system, making Mini ITX builds especially suitable for living room media centers, portable workstations, or desk setups where the PC is placed under a monitor or in a tight space.

Cooling System and Airflow Design

Thermal management is one of the biggest challenges in small form factor builds. To combat heat buildup, Mini ITX cases are engineered with strategic airflow in mind. Most come with one or two pre-installed fans—typically 92mm, 120mm, or 140mm—positioned for optimal intake and exhaust.

Advanced models support additional fans or even compact liquid cooling radiators (such as 120mm or 240mm), enabling efficient CPU and GPU cooling even under sustained workloads. Features like mesh front panels, elevated case positioning, and modular shrouds help enhance airflow while maintaining a sleek aesthetic.
