Hardkernel ODROID-H4 (Single-Board Computer/Intel N97/Quad-Core 3.6GHz x86/Up to 48GB DDR5/Budget x86 Mini-PC Board) Review
The ODROID-H4 is a genuine x86 mini-PC board built around Intel's N97 Alder Lake-N chip, at $99 it's a favorite among enthusiasts building budget NAS boxes, home routers, or pfSense/OPNsense firewalls who specifically need x86 compatibility rather than ARM. Up to 48GB of DDR5 memory support is unusually generous for a board this size and price, and a PCIe Gen 3 x4 NVMe slot gives genuinely fast primary storage.
The base H4 skips SATA ports entirely, buyers wanting mass storage should look at Hardkernel's own H4+ variant instead.
Why Enthusiasts Specifically Want x86 Here
A huge share of self-hosted networking and virtualization software (pfSense, OPNsense, Proxmox, certain NAS operating systems) either requires x86 or runs meaningfully better on it than on ARM. The ODROID-H4 fills that gap at a price point ARM boards dominate, letting enthusiasts run genuinely mainstream x86 server software on compact, low-power hardware.
Triple 4K Display Output for a Board This Size
One HDMI plus two DisplayPort outputs support up to three simultaneous 4K monitors, a notable capability for a board this compact and priced this low, useful for digital signage or compact desktop builds beyond its NAS/router reputation.
Comparison to Alternatives
Against our LattePanda Sigma, both are x86 boards, the Sigma's Intel Core i5-1340P delivers dramatically more CPU performance and Thunderbolt 4 at a much higher price, the H4 is the budget-conscious x86 pick for lighter workloads like routing and light NAS use. Against our Radxa ROCK 5C or Hardkernel's own ODROID-M2, both ARM-based, the H4's x86 architecture is the deciding factor for anyone specifically needing x86-only software.

Expert rating8 / 10
The budget x86 pick for NAS, router, and firewall builds where ARM compatibility isn't enough.
Best for
- Budget x86 NAS, router, and firewall builds (pfSense, OPNsense, Proxmox) needing genuine x86 compatibility.
- Compact digital signage or desktop setups needing triple 4K display output.
Not for
- Storage-heavy NAS builds, the base H4 has no SATA ports, look at Hardkernel's own H4+ variant instead.
