Understanding Motherboard Form Factors

Now that we’ve addressed the different computer case sizes, it’s essential to understand motherboard form factors and their compatibility with these cases. The form factor refers to a motherboard’s size, shape, and layout.

The most common motherboard form factors include Extended ATX (E-ATX), ATX, Micro-ATX, and Mini-ITX. Each form factor has its limitations and requirements concerning case compatibility, component support, and physical dimensions.

  • Extended ATX (E-ATX): As the largest form factor, E-ATX motherboards are suitable for high-end builds requiring multiple graphics cards and an extensive range of components. They are typically only compatible with Full Tower cases.
  • ATX: ATX motherboards are the most common choice for mainstream builds, offering a balance between component support, performance, and cost. They are compatible with Full Tower and Mid Tower cases.
  • Micro-ATX: Micro-ATX motherboards provide a compact solution for office PCs, budget gaming rigs, and smaller workstations. They are designed to fit into Full Tower, Mid-Tower, and Mini-Tower cases.
  • Mini-ITX: Mini-ITX motherboards are the smallest form factor and are suitable for SFF cases. They are designed to be portable and minimalist but sacrifice component compatibility and expandability.

Custom Watercooling Loops vs All-In-One CPU Coolers in Different Case Sizes

Investing in a reliable cooling solution is a must when it comes to keeping your components cool and ensuring your system runs efficiently. Custom watercooling loops and All-In-One (AIO) CPU coolers are popular among PC enthusiasts. In this section, we will discuss how each option interacts with the various case sizes and the factors to consider while choosing the best cooling solution for your build.

Custom Watercooling Loops

Custom watercooling loops provide an effective and highly customizable cooling solution for your computer’s components. While they can offer superior performance and aesthetics, they also require more space and planning for installation. Let’s take a look at how custom watercooling loops work with different case sizes:

Full-Tower Cases: With ample space for large radiators, reservoirs, and pumps, full tower cases are the most accommodating for custom watercooling loops. The spacious interior allows for complex and aesthetically pleasing loops that can handle extreme cooling requirements.

Mid-Tower Cases: Mid-tower cases balance size and cooling potential. While custom watercooling loops are still possible in these cases, you’ll likely need to plan your loop carefully to ensure all components fit comfortably and maintain the desired level of cooling performance.

Mini-Tower and SFF Cases: Implementing custom watercooling loops in smaller cases becomes increasingly challenging due to space constraints and component compatibility. While not impossible, these builds often require extensive planning, specialised parts, and creative configurations to achieve effective cooling.

All-In-One CPU Coolers

All-In-One (AIO) CPU coolers are closed-loop systems providing excellent cooling performance without the complexity and bulkiness of custom watercooling loops. They are pre-filled and sealed, making them easy to install and maintain. Here’s how AIO coolers interact with different case sizes:

Full Tower Cases: Thanks to their abundant interior, full tower cases are well-suited for large AIO coolers, offering optimal cooling performance. These cases can typically accommodate AIO coolers with 360mm radiators or larger, providing top-tier cooling for high-performance CPUs.

Mid-Tower Cases: Most mid-tower cases can easily support AIO coolers with 240mm or 280mm radiators, offering efficient cooling for mainstream builds. Depending on the case design, some mid-tower cases may even be able to accommodate 360mm radiators, further enhancing cooling potential.

Mini-Tower and SFF Cases: AIO coolers in smaller cases often require a more compact design, usually featuring 120mm or 140mm radiators. While these coolers may not provide the same level of cooling as larger AIOs, they still offer a substantial improvement over stock air coolers, especially in space-restricted cases.
