If you’ve started looking into home storage, home servers, or building a media library you can stream anywhere in the house, you’ve probably bumped into the same question: should you buy a dedicated NAS enclosure, or just use a mini PC running NAS software? Both approaches work. But they work differently, and the wrong choice can cost you time, money, and headaches.
This guide cuts through the confusion with a direct comparison across every dimension that actually matters: cost, power draw, flexibility, ease of use, and long-term upgrade potential. By the end, you’ll know exactly which path is right for your situation.
What Is a Dedicated NAS?
A NAS (Network Attached Storage) device is purpose-built for storing and serving files. Companies like Synology and QNAP design their hardware specifically around drive bays, low idle power, and their own operating systems. Synology runs DSM — a polished, app-based OS that even non-technical users can navigate. QNAP runs QTS, which is similarly approachable but with more advanced options.
The most popular entry-level models, like the Synology DS223j (two drive bays, ~$300 without drives), are designed to sit in a closet and just work. You install drives, follow the setup wizard, and you have network storage in about 20 minutes. No command line required.
What Is a Mini PC Running NAS Software?
A mini PC running TrueNAS, OpenMediaVault (OMV), or Unraid is essentially a general-purpose computer that’s been repurposed as a storage server. You take something like a Beelink Mini S12 Pro with an Intel N100, install a NAS operating system, connect external drives or a USB dock, and you have flexible network storage.
The key difference: the mini PC can also do everything else. Run Plex. Host Docker containers. Run Pi-hole for network-wide ad blocking. Act as a VPN server. A dedicated NAS can do some of these things too, but a mini PC does them without compromise.
Head-to-Head Comparison
| Factor | Dedicated NAS (Synology) | Mini PC + NAS Software |
|---|---|---|
| Starting Price | ~$300 (no drives) | ~$150 (Beelink N100) |
| Drive Bays | 2–8 internal 3.5″ bays | External USB dock required |
| Idle Power Draw | 8–15W | 6–12W (N100) |
| Ease of Setup | Very easy (GUI wizard) | Moderate (requires OS install) |
| Software Flexibility | Limited to DSM/QTS apps | Anything Linux can run |
| RAID Support | Built-in, easy | TrueNAS/OMV handle this well |
| Plex Transcoding | Limited (J-series CPUs are weak) | Strong (N100 handles 1–2 streams) |
| Upgrade Path | Add drives, limited CPU | Swap mini PC, swap drives |
| Warranty/Support | 3-year manufacturer warranty | Per-component |
The Case for a Dedicated NAS
If you’re not particularly technical and you just want something that works reliably with minimal fussing, a Synology NAS is genuinely hard to beat. DSM is one of the best operating systems in consumer technology — it’s polished, gets regular security updates, and has a huge app ecosystem. Synology’s Hybrid Share, Moments (photo management), and Drive (Google Drive alternative) are legitimately excellent.
Dedicated NAS hardware also tends to be better optimized for 24/7 operation with multiple spinning hard drives. The drive bay design, airflow, and firmware are built around HDDs specifically. If you’re building a large-capacity storage array with shucked WD or Seagate drives, a proper NAS enclosure keeps everything organized and well-cooled.
The Case for a Mini PC
Cost is the obvious argument. A Beelink Mini S12 Pro running the Intel N100 runs about $150–170. A Synology DS223j runs $300 before you add a single drive. For the price difference, you can buy two 4TB drives to populate your storage array.
The flexibility argument is even stronger. A mini PC running TrueNAS or OMV can simultaneously serve as your NAS, your Plex media server, your VPN, your ad-blocking server, and your home automation hub. Most entry-level Synology boxes struggle to run all of those at once because their processors — often ARM-based Realtek chips — simply aren’t powerful enough for transcoding or running multiple containers.
The N100’s Intel iGPU also supports hardware transcoding via Intel Quick Sync, which means Plex can transcode 1–2 streams simultaneously without breaking a sweat — at around 6 watts. A Synology DS223j running the same workload would struggle.
What About Power Costs?
Both approaches are relatively efficient. An N100 mini PC idles at around 6–9 watts depending on connected peripherals. A Synology DS223j idles at roughly 12–18W with two spinning drives loaded. Over a full year of 24/7 operation at $0.20/kWh, the power cost difference works out to roughly $6–20 annually — not a deciding factor, but worth knowing.
If you’re using shucked 7200RPM drives in a USB dock connected to your mini PC, factor in that those drives will add 5–9W per drive at idle. At that point, the power draw of both approaches becomes similar.
The Verdict: Who Should Choose What
Choose a dedicated NAS if: You want a plug-and-play experience, you’re building a large multi-drive array, you value Synology’s excellent software ecosystem, or you’re not comfortable installing a Linux-based OS. The DS223j or DS423+ are excellent starting points.
Choose a mini PC if: You want maximum flexibility, you’re comfortable with a moderate learning curve, you want to run Plex or Docker containers alongside storage, or you’re on a tight budget. An N100 mini PC running OpenMediaVault or TrueNAS SCALE is genuinely capable and costs significantly less up front.
For most readers of this site — people who’ve read about shucking drives and are comfortable with a bit of DIY — the mini PC route delivers more value. But don’t dismiss Synology. It’s a polished product that saves time, and time has value too.
Frequently Asked Questions
Can a mini PC replace a NAS completely?
Yes, for most home users. A mini PC running TrueNAS SCALE or OpenMediaVault can handle file sharing, RAID, Plex, and network services simultaneously. The main limitation is physical drive bays — you’ll need a USB dock for multiple HDDs.
Does TrueNAS run well on an N100 mini PC?
TrueNAS SCALE runs well on N100 hardware. You’ll want at least 8GB RAM (16GB preferred for ZFS) and a reliable boot drive. The N100’s performance is more than sufficient for home NAS workloads.
What’s the cheapest NAS setup possible?
A used N100 mini PC (~$130) plus a 2-bay USB 3.0 dock (~$40) plus two shucked drives (~$60 each) gets you a functional 8TB NAS for around $290 total — cheaper than a Synology DS223j without any drives.
