Introduction
At ZimaSpace, we are always thrilled to see how our community pushes the boundaries of what a single-board server can do. Today, we are featuring a fantastic deep-dive by the talented Gerard O’Brien from the YouTube channel Tech with Gerard.
In his latest video, Gerard takes the ZimaBoard 2 1664 (the 16GB RAM powerhouse) out of the box and puts it straight to work. From one-click app installs to building full virtual machines, Gerard demonstrates why this board is a game-changer for anyone looking to build a high-performance home lab. We want to extend a huge thank you to Gerard for his honest review and for showcasing the "secret sauce" behind ZimaOS.
Unboxing the Beast: Hardware That Defies Size
Gerard was immediately struck by the ZimaBoard 2 1664, noting its "industrial yet cute" design. But don't let the small form factor fool you; this is a professional-grade machine.
"Seriously, this thing powers up in seconds," Gerard noted. The hardware excellence is built into its connectivity:
Dual 2.5G Ethernet: Perfect for high-speed home lab networking and NAS (Network Attached Storage) applications.
-
PCIe 3.0 Slot: Allows for massive expansion, including 10G NICs (Network Interface Cards) or extra NVMe storage.
-
Native SATA Ports: Located at the back, allowing you to connect two additional hard drives to build a robust local server.
The board features a unique passive cooling structure (the "fins") that keeps the system completely silent and cool, even while running multiple heavy tasks.
ZimaOS: The "One-Click" Revolution
One of the highlights of Gerard’s review was the simplicity of ZimaOS. For many, setting up a server is a daunting task, but Gerard proved that you don’t need deep technical skills to get started.
"You could literally give this to anyone... you power it on, log in via a browser, and just click," Gerard explains.
The App Store: With over 381 apps available, self-hosting services like Jellyfin (a popular open-source media server) is as simple as clicking "Install."
-
Remote Access: ZimaOS allows you to configure external access easily, turning your board into a private cloud similar to Google Drive, accessible right from your phone.
Real-World Power: VMs and Containers
To truly test the 16GB RAM model, Gerard walked through three practical setup scenarios:
1. The Virtual Machine (ZVM)
Gerard utilized the ZVM tool to build a Virtual Machine (an emulation of a computer system).
- The Process: He selected a Linux Mint distribution, allocated CPU cores, and bridged the Ethernet.
-
The Result: The system booted directly into the live Linux environment flawlessly, all while remaining silent.
2. Manual Docker Containers
While the App Store is extensive, Gerard showed how to manually add a containerized application (a lightweight standalone package of software) using Pi-hole as an example.
- Pro Tip: Since ZimaOS uses Port 80 for its dashboard, Gerard showed how to map ports (e.g., mapping host port 8080 to container port 80) to avoid conflicts.
-
Efficiency: The Docker image pulled and installed in mere seconds.
3. The Ultimate Backup Hub
Gerard explored the Backup features, noting that you can potentially back up your Google Drive or replicate data from another NAS directly to the ZimaBoard 2, ensuring your home lab data is always secure.

The Verdict: A "Game-Changer" for Makers
Gerard’s final takeaway was clear: the performance-to-size ratio is incredible. While the board is a premium piece of hardware, the value comes from the integrated experience—you save money on cases, cooling, and adapters that other hobbyist boards require.
"I genuinely am shocked about how good this actually is," Gerard concluded. He even teased an upcoming project where he plans to turn a cluster of ZimaBoards into the ultimate Proxmox cluster (a platform for running virtual servers).
