The ZimaBoard 2 Pro is an ultra-compact, fanless x86 single-board server engineered for self-hosters, homelab architects, and edge computing developers. Powered by an Intel quad-core processor with hardware AES-NI cryptography, it delivers exceptional energy efficiency and continuous 24/7 silent operation.
Key Features & Highlights
- Dual Intel 2.5GbE Controllers: High-bandwidth network interfaces with full 802.3bz support, ideal for software routing (pfSense, OPNsense) and high-speed NAS setups.
- Standard PCIe 2.0 x4 Slot: Open expansion slot supporting 10GbE network cards, SAS HBAs, hardware transcoding accelerators, or NVMe M.2 carrier cards.
- Dual SATA 6Gbps Ports: Connect two 3.5” or 2.5” HDDs/SSDs directly with hardware power delivery leads.
- Pre-Installed CasaOS: Enjoy a clean, cloud-native personal dashboard with one-click Docker container deployment for Plex, Nextcloud, Home Assistant, and Jellyfin.

Outstanding micro server! Replaced a bulky noisy tower in my homelab with this ZimaBoard 2 Pro. It runs CasaOS with 14 Docker containers (Nextcloud, AdGuard Home, Vaultwarden, Jellyfin with hardware transcode) and idles at only 5.8W. Both 2.5GbE NICs achieve 282 MB/s continuous sustained transfer across my local fiber network.

Flawless build quality. The aluminum top heatsink keeps CPU package temperatures below 48°C under continuous iperf3 load. Having an actual PCIe x4 physical slot on an SBC of this size is a total game changer. Shipping from Flushing NY was super quick with great protective packaging.

Incredible x86 single board server! Deployed CasaOS and TrueNAS Scale in less than 20 minutes. Dual 2.5GbE ports saturate my local fiber LAN with zero packet loss. Outstanding passive thermal dissipation.
