DIY NAS: 2026 Edition
A 14-year NAS-building veteran shares his 2026 build ($1200, 8-bay, 10GbE) despite skyrocketing component prices, complete with the mistakes he made, real power consumption data, and $400 worth of cost-cutting alternatives.

TLDR
• Built around the Topton N22 motherboard with Intel N355 CPU (8 cores, 15W TDP) - adds 2 extra SATA ports over last year's model for 33% more storage capacity
• Real-world lessons: installed 4 drives backwards in the JONSBO N4 case because non-backplane bays access from the rear, not front - install those drives first
• Actual numbers: 66W average power draw, saturates 10GbE network (1104 MB/s sequential write to NVMe pool over SMB), costs $989 without drives
• EconoNAS path: swap to N100 CPU, 16GB RAM, cheaper PSU and fan saves $400+ while maintaining nearly equivalent performance
• Off-the-shelf alternatives (QNAP, Asustor) cost $880-1200 but lack upgrade paths - can't swap motherboard, RAM, or add expansion cards years later
In Detail
After 14 years of annual DIY NAS builds, the author confronts 2026's brutal economics head-on: SSD, RAM, and motherboard prices are all rising, yet he argues it's still worth building. The centerpiece is the Topton N22 motherboard with Intel Core 3 N355 (8 cores, 15W TDP, $446), which adds two SATA ports over last year's N18 for eight total drives. Paired with the JONSBO N4 case ($122), 32GB DDR5 RAM, and 10GbE networking, the complete build hits $989 before storage.
The author shares hard-won assembly lessons: the JONSBO N4's four non-backplane drive bays access from the rear, not front - he installed all drives backwards before realizing his mistake. His fix: install those four drives and cables first, before anything else. He also replaced the stock case fan with a Noctua unit connected to the motherboard's SYS_FAN header for quieter, tunable cooling. Real benchmarks show 66W average power consumption (90W idle, 107W under load), 1104 MB/s sequential writes over 10GbE SMB to the NVMe pool, and the ability to saturate the 10Gb network connection.
For budget builders, he outlines an "EconoNAS" path: downgrade to the N100 or N150 CPU (-$180-224), use 16GB RAM (-$39), swap to a Thermal Right fan (-$26) and Apevia PSU (-$104), skip boot drive redundancy (-$22). These changes save $400+ while maintaining near-equivalent performance. He contrasts this with off-the-shelf options like the QNAP TS-832PX ($880) or UGREEN DXP8800 ($1200), arguing DIY's real advantage is upgradeability - you can swap the motherboard, RAM, or add PCI-e cards years later, which commercial NAS units can't do. The build runs TrueNAS 25.10 and he's auctioning the completed unit on eBay with no reserve.
