Hardkernel ODROID-H3 (Single-Board Computer/Intel Celeron N5105/Quad-Core x86 2.9GHz/Up to 32GB DDR4/Dual 2.5GbE Mini-PC Board) Review
Hardkernel ODROID-H3 x86 single-board computer with an Intel Celeron N5105 quad-core CPU, up to 32GB DDR4 SODIMM RAM, dual 2.5 Gigabit Ethernet, dual SATA3 ports, and an M.2 NVMe slot for a compact self-built NAS or router.
The H3 drops the ARM ecosystem entirely and gives you a real x86 board instead -- meaning full x86-64 software compatibility, proper TrueNAS/pfSense/OPNsense support, and SATA ports for spinning-disk NAS builds, all in a board barely bigger than a Pi HAT stack.
Overview
Hardkernel's H-series abandons ARM for Intel's Jasper Lake platform, giving up GPIO headers and the ARM software ecosystem in exchange for unrestricted x86-64 compatibility -- meaning any Linux, BSD, or Windows-on-x86 software just runs, no ARM porting required.
Performance & Connectivity
Two 2.5GbE ports handle router or NAS duty at real multi-gigabit speeds, two SATA3 ports support hard drives directly, and an M.2 NVMe slot adds fast boot/cache storage. Up to 32GB of DDR4 makes it viable for ZFS-based NAS builds that benefit from generous RAM for caching.
Comparison to Alternatives
Against the UP 4000, another x86 board in this category, the H3 focuses purely on networking and storage rather than GPIO or embedded use, and its dual SATA ports make it the stronger choice for disk-based NAS. Compared to ARM alternatives like the Hardkernel ODROID-M1, the H3 sacrifices power efficiency and cost for full x86 software compatibility.

Expert Review
Reviewed by Burooj Alam. Rated by us, not by users.
Expert rating8.1 / 10
The board to reach for when a NAS or router project specifically needs x86 compatibility, SATA ports, or software that simply doesn't exist for ARM.
Best for
- TrueNAS or ZFS-based file servers using SATA drives
- pfSense/OPNsense router builds needing 2.5GbE
- x86 software compatibility for legacy or niche tools
Not for
- GPIO or embedded electronics projects (no header)
- Power-sensitive or fanless-at-all-costs designs
- Buyers who just want the cheapest possible NAS board
