Recommended ATX Motherboards for DIY NAS Builds

Six ATX/MATX/EATX Motherboards for Your BYO NAS Build

Building your own NAS (Network Attached Storage) offers unparalleled control over your storage solution, but choosing the right motherboard is crucial. While ITX motherboards are commonly used for compact builds, ATX motherboards excel in scalability and performance. This guide explores six top ATX motherboards suitable for DIY NAS builders and explains why ATX might be the right choice for your project.

ATX vs. ITX: Understanding the Differences for NAS Use

ITX motherboards have long been favored for NAS systems due to their compact size, lower power consumption, and often pre-included mobile CPUs. These features make them ideal for smaller, quieter builds with minimal hardware requirements. However, ITX boards typically offer fewer PCIe slots, fewer SATA ports, and limited M.2 storage options, which can restrict scalability for larger storage systems. In contrast, ATX motherboards shine in builds where storage and expansion are priorities. They offer multiple PCIe slots for RAID cards, network cards, and GPUs, along with extensive SATA and M.2 connectivity. While ATX motherboards tend to consume more power and require larger cases, they cater to the growing demands of NAS builders who need flexibility and performance. If you’re planning to scale your NAS system or integrate high-speed networking, ATX is often the better choice despite its higher price point and larger physical footprint.

Motherboard form factors play a critical role in determining a system’s size, expandability, and compatibility. mATX (Micro-ATX), ATX (Advanced Technology Extended), and E-ATX (Extended ATX) represent progressively larger sizes, each catering to different use cases. mATX motherboards are compact and typically measure 9.6 × 9.6 inches, making them ideal for small cases and builds that prioritize a smaller footprint. However, they often sacrifice expandability, offering fewer PCIe slots, SATA ports, and overall connectivity. Standard ATX motherboards, measuring 12 × 9.6 inches, strike a balance between size and functionality, providing ample room for multiple PCIe slots, more storage options, and better cooling configurations. Finally, E-ATX motherboards, measuring up to 12 × 13 inches, cater to high-performance builds such as workstations or enterprise systems. They offer additional PCIe lanes, memory slots, and connectivity options but require larger cases and often consume more power. The choice between these form factors depends on your specific needs for expandability, performance, and the physical constraints of your build.
