10 Best mini PC for plex media server

From leading brands and best sellers available on the web.

Buying Guide for the Best mini PC for plex media server

When shopping for a mini-PC to use as a Plex media server, it's important to consider how you'll be using Plex: whether you'll be streaming to just a couple of devices around your home, or if you'll need more powerful features like transcoding for multiple users at once, remote streaming, or 4K content. A good Plex server means stable, responsive streaming and the ability to handle video files efficiently. By focusing on some key specifications, you can make sure your chosen mini-PC will deliver a smooth experience both now and as your media needs grow.
CPU (Processor)The CPU is like the brain of your mini-PC, playing a major role in how well it can handle tasks like streaming or transcoding video files. For simple streaming—sending files as-is to devices that natively support them—a less powerful processor might be enough. However, if your Plex server needs to transcode (convert) video formats for devices that can't play the original file, you'll want a stronger processor. Entry-level CPUs with fewer cores are suitable for basic home streaming, mid-range CPUs are good for one or two simultaneous transcodes, and stronger CPUs with multiple cores are best if you expect heavy use, remote access, or want to future-proof as your library grows.
RAM (Memory)RAM helps your system keep things running smoothly, especially when dealing with multiple streams or library management. For a lightweight setup or single-user use, a small amount of RAM (4 GB) will work, but as you add users, plugins, or larger libraries, stepping up to 8 GB or even 16 GB can help ensure smooth performance without stutters or slow navigation. Choose higher RAM if you anticipate several people streaming at once or if you have a huge media library.
StorageStorage is where your media files live. There are two aspects to consider: capacity and speed. For capacity, think about the size of your media collection and future growth—smaller drives (120-256 GB) might be fine for just the operating system and metadata, but you'll need much more (1 TB or greater) if storing lots of movies or 4K content. For speed, solid-state drives (SSDs) help with faster booting, quicker library scans, and better overall responsiveness compared to traditional hard drives (HDDs). If your collection grows constantly, make sure the mini-PC has room for more drives or supports external storage devices.
Network ConnectivityA good network connection ensures smooth video streaming, especially for high-quality or multiple simultaneous streams. Mini-PCs may offer Ethernet (wired) or Wi-Fi (wireless) options. Wired Ethernet, especially Gigabit, is best for reliable and fast plex streaming, particularly for 4K content or multiple users, while high-speed Wi-Fi (Wi-Fi 5 or Wi-Fi 6) can be sufficient for moderate use and greater flexibility. Consider your home network setup—if you can connect your Plex server directly to your router with a cable, you'll usually get the best experience.
Form Factor and PortsThe physical size and connectivity options of a mini-PC matter based on where you'll place it and what devices you'll connect. Compact units are easy to tuck away and keep things neat, but make sure the mini-PC offers enough USB, HDMI, or other necessary ports for your accessories, external drives, or monitor (during initial setup and troubleshooting). Consider the form factor for your available space and the flexibility you might need in the future.
Noise and CoolingSince mini-PCs can be used in living rooms or bedrooms, the level of noise they generate is worth considering. Some mini-PCs are fanless and virtually silent, while others use small fans that can be heard when working hard. If you’re sensitive to background noise, especially in quiet rooms, or plan to leave the server running 24/7, quieter or passive-cooled options are more comfortable. Make sure that the cooling system is adequate to handle long streaming sessions without overheating.
