10 Best Smallest Atx Cases For Compact Pc Builds In 2024 – Power In A Tiny Package

As the world of technology continues to progress, it’s no surprise that people are increasingly seeking out space-saving solutions for their computing needs. One such trend is the growing interest in compact ATX cases, which are perfect for those looking to maximize the performance of their PC builds while minimizing the physical footprint.

In this comprehensive guide, we will delve into the world of the smallest ATX cases available, providing you with valuable insights and recommendations to help you choose the perfect case for your next compact PC build.

What Is an ATX Case, and Why Go Compact?

ATX (Advanced Technology eXtended) is a motherboard and power supply configuration standard introduced by Intel in 1995. ATX cases, as the name suggests, are designed to accommodate ATX motherboards and their components. These cases have become the most popular choice for PC builders due to their versatile layouts and broad compatibility with various hardware components.

Compact ATX cases, on the other hand, are specifically designed to house ATX motherboards and components within a smaller, more space-efficient chassis. These cases are perfect for individuals with limited space, as they allow for high-performance PC builds without taking up too much room. Additionally, compact ATX cases can be more portable, making them a great choice for those who travel often or attend LAN parties.

Key Factors to Consider When Choosing a Compact ATX Case

Before diving into our top picks for the smallest ATX cases, it’s essential to consider several key factors that will help you make the best decision for your specific needs:


While all compact ATX cases are designed to be smaller than standard ATX cases, some are more compact than others. Be sure to measure the available space you have and compare it with the dimensions of the case you’re interested in.


High-performance components generate heat, and compact cases have less space for airflow. Ensure the case you choose has adequate ventilation, space for fans or liquid cooling systems, and proper cable management to avoid thermal issues.


Consider the number of storage and expansion slots you’ll need for your build. Some compact cases may have limited options, so it’s crucial to ensure the case can accommodate your hardware requirements.

Design and Aesthetics

Your PC case will be visible in your workspace or gaming area, so it’s essential to choose a design that suits your style and preferences.
