The Raspberry Pi is the original DIY home server. Millions of homelab builders started with one. But in 2026, mini PCs have closed the price gap significantly while delivering dramatically more capability. The question isn’t “which is cheaper” — it’s “which is the right tool for your actual workload?”
This comparison gives you a direct, honest answer based on real-world capability differences.
The Short Answer
Buy a Raspberry Pi if: You want to run Pi-hole, Home Assistant, or a single lightweight service on a $35–80 device that draws under 5W and you don’t need more than 8GB RAM.
Buy a mini PC if: You want to run multiple containers, any VMs, Plex/Jellyfin transcoding, Nextcloud, or any service requiring more than 4GB RAM — or if you want 64-bit x86 compatibility for the full Docker ecosystem.

Detailed Breakdown
CPU Architecture: The Fundamental Difference
The Raspberry Pi 5 uses an ARM64 CPU. The Beelink EQ14 and SER9 PRO+ use x86-64. This isn’t just a specs difference — it changes what software you can run.
Most Docker images are built for x86-64 first. ARM64 images exist for popular software (Pi-hole, Home Assistant, Vaultwarden), but niche images often don’t. If you’re running standard containers, ARM64 coverage is 80% adequate. If you’re running anything obscure — specific databases, monitoring tools, legacy apps — x86 compatibility becomes critical.
Proxmox requires x86-64 with VT-x. Running KVM virtual machines on a Raspberry Pi is not supported. You can use lightweight containers (LXC is x86-specific too), but full VM virtualization is off the table on ARM.
Winner for Docker: Mini PC (x86 compatibility) Winner for basic containers: Tie — RPi handles Pi-hole, HA, and most common containers
RAM
The Raspberry Pi 5 tops out at 8GB, and it’s soldered. 8GB is enough for Pi-hole, Home Assistant, and 3–5 lightweight containers. If you add Plex, Nextcloud, or any database-heavy service, 8GB gets tight.
The EQ14 supports 32GB DDR4 in two upgradeable SO-DIMM slots. The SER9 PRO+ has 32GB LPDDR5X soldered — not upgradeable, but sufficient for most workloads. If your workload grows beyond 32GB, the EQ14 or UM790 Pro scale further. The Raspberry Pi doesn’t.
Winner: Mini PC — no contest for RAM headroom
Storage
The Raspberry Pi 5 can use a microSD card (slow, unreliable for 24/7 workloads) or a PCIe M.2 NVMe HAT (additional $15–30 cost). With the HAT, you get comparable NVMe speeds to mini PCs, but it adds cost and complexity.
Mini PCs ship with a standard M.2 NVMe slot included. No add-ons needed.
Winner: Mini PC — NVMe built-in, no extra cost
Networking
The Raspberry Pi 5 has a single 1GbE port. In 2026, 1GbE is adequate for most home use but a limitation for NAS, media serving, or high-throughput workloads.
The Beelink EQ14 ships with dual 2.5GbE ports — ideal for OPNsense or network segmentation. The SER9 PRO+ has a single 2.5GbE port but adds USB4 and Wi-Fi 6. For a home server where dual NICs matter, the EQ14 is the right pick.
Winner: Mini PC
Power Consumption
The Raspberry Pi 5 is a power champion: ~3–5W idle, ~8–10W under load. Running 24/7 for a year at $0.12/kWh costs ~$3.15–5.26.
The EQ14 draws ~6W idle — close, but about $3/year more. The SER9 PRO+ at ~8W idle costs ~$8.40/year. For the EQ14 specifically, the power difference vs. a Raspberry Pi 5 is ~$3/year — essentially nothing.
Winner: Raspberry Pi — though the gap is minimal for budget mini PCs
Price
| Device | Base Price | Total Ready-to-Run Cost | Link |
|---|---|---|---|
| Raspberry Pi 5 (8GB) | ~$80 | ~$130–150 (add case, PSU, NVMe HAT, microSD) | Check Price |
| Beelink EQ14 | ~$190 | ~$190 (NVMe and PSU included) | Check Price |
| Beelink SER9 PRO+ | ~$380 | ~$380 | Check Price |
The Raspberry Pi 5 starter price is lower, but the “all-in” cost with accessories is closer to $130–150. The EQ14 at ~$190 is only $40–60 more for significantly more capability.
Winner: Raspberry Pi at raw component cost, but the gap narrows significantly when you add up accessories
Use Case Comparison
Run Pi-hole: Raspberry Pi wins on cost, tie on capability
Pi-hole runs perfectly on a Raspberry Pi 4 or 5. It uses ~64MB RAM and minimal CPU. If Pi-hole is your ONLY use case and you have a spare RPi, use it. If you don’t have one and need to buy hardware, the $40–60 Raspberry Pi 5 price advantage doesn’t justify the long-term capability limitations.
Run Home Assistant: Tie
Home Assistant OS runs well on both platforms. The official Raspberry Pi image is mature and well-supported. For HA-only, the Pi is the right choice. For HA alongside other services, the mini PC’s extra RAM headroom wins.
Run Proxmox with VMs: Mini PC only
Not possible on Raspberry Pi. Full stop. If VMs are in your plan — ever — buy a mini PC.
Run Plex / Jellyfin with transcoding: Mini PC only
The Raspberry Pi lacks hardware transcoding for H.265/HEVC and can’t handle 4K transcoding. The EQ14’s Intel Quick Sync handles multiple 1080p and one 4K transcode stream efficiently. The SER9 PRO+‘s Radeon 780M handles demanding workloads.
Run 10+ Docker containers: Mini PC wins
10 containers averaging 128MB each = 1.3GB RAM. The Pi’s 8GB handles this. But when you add a database, Plex, Immich, and your actual data layers, you’re at 4–6GB of RAM usage easily. 8GB becomes uncomfortably tight. 16–32GB on an EQ14 gives you room to grow.
Always-on 24/7 server in a power-sensitive setup: Raspberry Pi
If you’re running from a solar battery, an off-grid setup, or a UPS with limited capacity, 3–5W vs. 6–8W is a real consideration. The Raspberry Pi wins on ultra-low-power scenarios.

Frequently Asked Questions
Is a Raspberry Pi good enough for a home server?
For Pi-hole, Home Assistant, and 3–5 lightweight containers, yes. The Raspberry Pi 5 handles typical single-function homelab tasks well. Where it falls short: VMs, 4K transcoding, RAM-heavy applications, and x86-only Docker images.
Why do mini PCs cost more than Raspberry Pi?
Mini PCs include a full x86 CPU, NVMe storage, a metal chassis, and a power supply. The Raspberry Pi is just the board — add a case, power supply, microSD or NVMe HAT, and heat sink, and the cost gap narrows to $40–60 for budget options.
Can a Raspberry Pi run Proxmox?
No. Proxmox VE requires x86-64 hardware with Intel VT-x or AMD SVM. The ARM architecture of the Raspberry Pi is not supported. For VM hosting, you need an x86 mini PC.
What can a Raspberry Pi do that a mini PC can’t?
The Raspberry Pi has a GPIO header (General Purpose I/O pins) for hardware projects — controlling relays, sensors, motors, and custom electronics. For maker projects, robotics, or IoT hardware interfacing, the GPIO is irreplaceable. Mini PCs don’t have GPIO.
Is the Raspberry Pi 5 worth the upgrade from Pi 4?
For home server use, yes — the Pi 5 is meaningfully faster with better PCIe support for NVMe storage. For existing Pi 4 users running Pi-hole and Home Assistant, the upgrade isn’t urgent. For new builds where the Pi is the right choice, buy the Pi 5.
What’s the best Raspberry Pi alternative that’s still ARM?
If you specifically want ARM for power savings and the RPi is out of stock or too expensive, the ODROID-N2+ and ROCK 5B are capable alternatives. But for most homelab use cases, the x86-64 EQ14 at ~$190 is a better investment.
Final Verdict
| Scenario | Recommendation |
|---|---|
| Pi-hole only | Raspberry Pi 4 or 5 |
| Home Assistant only | Raspberry Pi 4 or 5 |
| Pi-hole + Home Assistant + a few containers | EQ14 (if budget allows) or RPi (if already owned) |
| Proxmox, any VMs | Mini PC — EQ14 minimum |
| Plex / Jellyfin with transcoding | Mini PC — EQ14 minimum |
| 10+ Docker containers | Mini PC — EQ14 minimum |
| Docker + Nextcloud + media | Mini PC — SER9 PRO+ or EQ14 |
| Maximum capability, future-proof | Mini PC — SER9 PRO+ or GMKtec K11 |
The Raspberry Pi is not obsolete — it’s the right tool for simple, single-purpose setups, especially if power consumption is critical or you already own one. For any multi-service homelab, the economics of a mini PC pay off quickly: the ~$60 premium over an all-in Raspberry Pi 5 build buys you x86 compatibility, upgradeable RAM, and a 24/7-reliable NVMe — capabilities you’ll want within 6 months of getting started.
