Building a DIY NAS in 2026: Key Considerations and Trends

Fourteen years ago, my need for more storage prompted me to create a custom network-attached storage (NAS) server. I set specific criteria and sought community advice, but found most forums unhelpful or hostile toward my approach. This motivated me to build my own DIY NAS and share that journey through a blog, which surprisingly gained significant interest.

Since then, I’ve been developing new DIY NAS systems annually to inspire others. My main requirements included a small size, multiple drive bays, efficient power usage, and potential for home lab practices. Although these criteria worked for me, I emphasize that each builder should tailor their own list based on personal needs.

Space was initially a concern, leading to a compact design. I aimed for at least six drive bays, providing ample room for current storage and future expansion, acknowledging that SSDs and HDD capacities have grown significantly over time. I also prioritized an energy-efficient, low-power CPU to support 24/7 operation without high electricity costs. Additionally, I wanted my NAS to serve as a platform for virtual machines, containers, and self-hosted services, making room for homelab potential.

Given current economic conditions, component prices, including hard drives, SSDs, RAM, motherboards, and CPUs, are rising. Some suppliers advise stocking up on components like motherboards before prices climb or availability drops. The economic downturn makes this a challenging time for DIY builders, and I contemplated postponing my build, but I worried conditions could worsen.

For my 2026 NAS, I selected the Topton N22 motherboard paired with an Intel Core 3 N355 processor. Since 2023, I’ve used Topton motherboards exclusively, despite some concerns about sourcing from international vendors. The N22 offers incremental improvements over the previous year’s model, including extra SATA ports, a PCI-e slot, and a powerful yet energy-efficient processor.

This build features the Mini-ITX form factor, an 8-core CPU with 8 threads, reaching a maximum turbo frequency of 3.9 GHz, all within a 15W TDP. Its integrated GPU enhances multimedia capabilities, making it a versatile platform for data storage and home lab experimentation.

In conclusion, building a DIY NAS remains a practical and flexible option for personalized data management and experimentation. However, economic factors are causing component prices to rise, prompting early planning and purchasing. With careful selection of hardware like the Topton N22 and Intel Core 3 N355, users can create efficient, expandable NAS systems suited to their unique needs.
