What a Budget Home NAS Is and Why a Mini PC Works
A budget home NAS is a low-cost network-attached storage setup that reuses modest hardware, such as a secondhand mini PC, to share files, media, and backup storage across your home network using free or open-source software instead of expensive commercial appliances. Mini PCs fit this role well because they are compact, sip power, and offer enough CPU and RAM for everyday self-hosted apps. According to How-To Geek, old office mini PCs on Facebook Marketplace can cost around USD 50 (approx. RM230) and still handle basic home server tasks once you install a Linux server OS. Devices like the Acemagic Kron Mini K1, or even retired handheld PCs, provide the core of a mini PC server setup without the need for a noisy tower or a dedicated equipment closet, making a DIY NAS build accessible and practical.

Choosing the Right Secondhand Mini PC for Your NAS
Start your budget home NAS by finding a secondhand mini PC with a sensible balance of CPU, RAM, and ports. Marketplace listings commonly include Intel Pentium, Celeron, or older i3/i5 chips with 2 GB–8 GB of RAM and a small SSD, plus USB 2.0/3.0 and Gigabit Ethernet, which is enough for a starter mini PC server setup. If you want more headroom, look for hardware similar to the Acemagic Kron Mini K1, which ships with an AMD Ryzen Embedded R2544, 8GB DDR4 and dual M.2 slots that can scale up to larger storage. Focus on reliable networking and plenty of USB or M.2 options for adding drives. You can run it headless with only power and Ethernet connected, allowing it to live quietly on a shelf while serving files across the house and keeping power consumption low.

Installing ZimaOS for a User-Friendly Home Server
To turn your secondhand mini PC into a ZimaOS home server, you first wipe or replace the existing operating system with a lightweight Linux-based environment. ZimaOS brings a browser-based dashboard, app store, and storage management that feels more like a commercial NAS than a barebones Linux box. On a device like the Kron Mini K1, freeing resources from Windows bloat means the 4-core/8-thread Ryzen Embedded R2544 can focus on 24/7 server tasks instead of desktop overhead. Once installed, you can configure shared folders, connect external hard drives for bulk media, and add containers for services such as Jellyfin, backup tools, or download managers. The compact form factor and efficient chipset mean the system can stay powered on around the clock without drawing as much power as a full tower, yet still remain quick enough for multiple simultaneous streams or file transfers.

Adding RomM and Media Apps for Retro Gaming and Streaming
With ZimaOS running, your DIY NAS build can become more than a file locker by installing RomM and other media apps. RomM is designed to organize and serve retro gaming libraries, turning your mini PC server setup into a central hub for ROMs and box art. The Kron Mini K1’s Ryzen Embedded R2544 and upgradable RAM allow it to manage a sizable catalog while still hosting other services. Pair RomM with a self-hosted media server such as Jellyfin to stream movies, shows, and music throughout the home instead of relying on third-party platforms. Storage can be expanded with additional M.2 SSDs inside the chassis or external hard drives connected over USB. Once configured, consoles, handhelds, smart TVs, and PCs on your network can access the same curated library, making retro gaming and personal media easy to enjoy from any room.

Everyday Benefits of a Compact Always-On Server
Running a budget home NAS on a secondhand mini PC gives you a quiet, reliable appliance that blends into your living space. Mini PCs are small enough to sit behind a monitor or on a shelf, and they draw far less power than traditional desktops or rack servers while still handling file sharing, backups, and media streaming. One How-To Geek article notes that mini PCs “sip power compared to proper desktop and server hardware, and still have enough performance to handle basic self-hosted apps.” Always-on availability means your devices can back up photos, sync documents, or stream media at any time without waking a laptop. As your needs grow, you can scale storage with more drives or upgrade RAM, but the same compact chassis remains the heart of your self-hosted stack, giving old hardware a long, useful second life.
