Raspberry Pi vs Mini PC for Your Homelab: Which Should You Buy?

This is the most common question new homelabbers ask. The answer depends entirely on what you want to run — and most guides don't give you a straight answer.

Here's a direct comparison, no hedging.

The Short Answer

Get a Raspberry Pi if: You want to run Pi-hole, WireGuard, or a few lightweight containers on a tiny always-on device and you want to spend $75-100 total.

Get a used mini PC if: You want to run Nextcloud, Jellyfin, or anything involving file storage, media transcoding, or more than 3-4 containers simultaneously.

Most people who start with a Pi end up buying a mini PC within 6 months. If your budget allows it, skip straight to the mini PC.

Raspberry Pi 4/5: What It's Good At

The Pi is a genuinely great device for specific use cases:

Pi-hole — ad blocking at the DNS level for every device on your network. The Pi uses about 3 watts running this. Leaves your old PC free for more demanding tasks.

WireGuard VPN — a lightweight VPN server that lets you securely access your home network from anywhere. Runs perfectly on a Pi.

Vaultwarden — self-hosted Bitwarden password manager. Low resource usage, works great.

Home Assistant — smart home automation hub. This is actually one of the best Pi use cases.

PiAlert / network monitoring — keeping an eye on what's on your network.

Where it struggles:

  • Jellyfin with transcoding — the Pi can serve files if the client supports direct play, but any transcoding will choke it. 4K is basically impossible.
  • Nextcloud with many files — works for basic file sync, but search and thumbnail generation are painfully slow.
  • Multiple containers — once you're running 5+ services, the 4GB or 8GB of RAM fills up fast.
  • Storage — the Pi uses a microSD card or USB drive. MicroSD cards fail under constant read/write loads. You'll need an SSD via USB, which adds cost and a power brick.

Cost reality: Pi 4 8GB + case + power supply + SSD = ~$120-150 by the time it's properly set up. That's not that far from a used mini PC.

Used Mini PC: The Better Value for Most People

A used Intel NUC, Beelink mini PC, or similar from eBay runs $80-200 depending on specs. For that price you get:

  • Intel N100 or similar — 4 cores, handles Jellyfin 4K transcoding via Intel Quick Sync
  • 8-16GB RAM — run 10+ containers without sweating
  • M.2 SSD slot — fast, reliable storage (no USB drives, no SD cards)
  • Real x86 processor — every Docker image works without compatibility issues (some ARM images are missing or buggy)
  • Low power — 10-15 watts under load, still extremely efficient

The ARM problem: The Pi runs ARM architecture. Most Docker images support it, but occasionally you'll hit a container that only has x86 builds. On a mini PC this never happens.

Recommended models (check eBay):

  • Intel NUC 10/11 — rock solid, widely supported
  • Beelink EQ12 or Mini S12 — newer N100 chip, excellent value
  • ASUS PN50/PN51 — AMD option, good for GPU-assisted tasks
  • HP EliteDesk 800 G3 mini — enterprise-grade, cheap used, plentiful

Target spec: N100 or i5/i7 8th gen+, 16GB RAM, 256GB+ SSD. Budget $100-180 on eBay.

Direct Comparison

Raspberry Pi 4 (8GB) Used Mini PC (N100)
Cost ~$120-150 all-in $100-180
Power use 5-8W 10-15W
RAM 8GB max 8-32GB
Storage USB SSD (awkward) M.2 SSD (clean)
Architecture ARM x86
Jellyfin 4K ❌ ✅
Nextcloud Slow ✅
Pi-hole ✅ Perfect Overkill
Docker compatibility Occasional issues ✅ Everything
Noise Silent Near-silent
Size Credit card Paperback book

The "Both" Setup (Best Long-Term)

Many homelabbers run both:

  • Pi for Pi-hole (always on, dedicated, 3 watts)
  • Mini PC for everything else (Nextcloud, Jellyfin, Vaultwarden, Home Assistant, etc.)

This way your ad blocking stays up even if you restart the main server for updates.

Total cost for this setup: $200-250. Monthly power cost: $2-4.

What To Buy Right Now

Tight budget ($75-100): Raspberry Pi 4 4GB + SSD. Run Pi-hole, WireGuard, Vaultwarden. Learn Docker on it. Understand what you actually want to run before spending more.

Normal budget ($120-180): Beelink EQ12 (N100, 16GB RAM, 500GB SSD) from Amazon or a used NUC from eBay. Run everything. This is the "right" answer for most people.

Already have a spare PC: Use it. Any PC from the last 10 years with 8GB+ RAM runs a full homelab. Save your money.

Getting Started

Whichever hardware you choose, the software setup is the same:

  1. Install Ubuntu Server
  2. Install Docker
  3. Pick your first 3 apps from the list above
  4. Start with something you'll actually use (Pi-hole if you hate ads, Vaultwarden if you use a password manager, Jellyfin if you have media)
