Choosing the Right Hardware
NAS Devices
A Network Attached Storage device is the workhorse of most home setups. It stores your files, runs Docker containers, handles backups, and serves media.
Synology vs QNAP vs DIY
| Feature | Synology | QNAP | DIY (TrueNAS/Unraid) |
|---|---|---|---|
| OS quality | Excellent (DSM) | Good (QTS) | Excellent (TrueNAS/Unraid) |
| Docker support | Yes (Container Manager) | Yes (Container Station) | Yes (native) |
| App ecosystem | Large, curated | Large, less polished | Unlimited |
| Setup difficulty | Very easy | Easy | Medium–Hard |
| Hardware flexibility | None (locked) | None (locked) | Complete |
| Price (2-bay) | £250–400 | £200–350 | £200+ (you build) |
| ECC RAM support | Some models | Some models | Your choice |
Recommended NAS Models (2025/2026)
Budget (£200–300):
- Synology DS224+ — Intel Celeron J4125, 2GB RAM (expandable to 18GB), 2x 3.5" bays. Does everything a home user needs.
Mid-Range (£300–500):
- Synology DS423+ — 4-bay, Intel Celeron J4125, 2GB RAM (expandable). Perfect for growing storage needs with room for an SSD cache.
Power User (£500+):
- Synology DS923+ — AMD Ryzen R1600, 4GB RAM, 4-bay with 10GbE optional. Proper Docker performance.
- QNAP TS-464 — Intel N5105, 8GB RAM, 4-bay, dual 2.5GbE. Strong hardware for the price.
Mini PCs for Docker Hosting
If your NAS isn't powerful enough for heavy Docker workloads, a mini PC makes an excellent dedicated server.
The Intel N100 Generation
The Intel N100 processor (and N95/N97 variants) represents remarkable value: 4 cores, 6W TDP, and enough performance for 20+ Docker containers.
| Model | CPU | RAM | Storage | Ethernet | Price |
|---|---|---|---|---|---|
| Beelink Mini S12 Pro | N100 | 16GB | 500GB SSD | 1x 1GbE | ~£140 |
| MinisForum UM350 | Ryzen 5 3550H | 16GB | 512GB | 1x 1GbE | ~£200 |
| Protectli VP2420 | J6412 | 16GB | 128GB | 4x 2.5GbE | ~£350 |
| Lenovo ThinkCentre M720q | i5-8500T | 16GB | 256GB | 1x 1GbE | ~£100 (refurb) |
Best value: Beelink Mini S12 Pro. Silent, tiny, enough for most self-hosting needs.
Best for networking: Protectli VP2420. Four NICs makes it ideal as an OPNsense/pfSense router.
Routers & Firewalls
Your ISP's router is almost certainly terrible. Replacing it (or putting a proper router behind it in bridge mode) improves speed, security, and control.
Router Options
| Solution | Hardware | Cost | Best For |
|---|---|---|---|
| ISP router + Pi-hole | Existing | Free + £35 | Minimal improvement |
| OpenWrt on existing router | Existing | Free | Budget upgrade |
| Mini PC + OPNsense | Mini PC | £100–350 | Full control |
| UniFi Dream Machine | Dedicated | ~£300 | Ecosystem integration |
| MikroTik hEX | Dedicated | ~£50 | Advanced networking on budget |
Storage Drives
Hard Drives (NAS-Rated)
| Drive | Capacity | RPM | Cache | Warranty | Price/TB |
|---|---|---|---|---|---|
| WD Red Plus | 4–14TB | 5400/7200 | 256MB | 3 years | ~£20/TB |
| Seagate IronWolf | 4–20TB | 5400/7200 | 256MB | 3 years | ~£19/TB |
| WD Red Pro | 4–22TB | 7200 | 512MB | 5 years | ~£25/TB |
| Seagate IronWolf Pro | 4–24TB | 7200 | 256MB | 5 years | ~£24/TB |
| Toshiba N300 | 4–18TB | 7200 | 256MB | 3 years | ~£18/TB |
For most home users: WD Red Plus 4TB or 8TB drives offer the best balance of price, reliability, and noise levels. Buy them in matched pairs for RAID 1 or SHR (Synology Hybrid RAID).
SSDs for Cache and Boot
NVMe SSDs dramatically speed up NAS operations when used as read/write cache:
- Samsung 970 EVO Plus 250GB — Excellent endurance, ~£40. A 250GB cache drive is plenty for most NAS setups.
- WD Red SN700 500GB — NAS-optimised firmware, ~£50.
UPS (Uninterruptible Power Supply)
A UPS protects your equipment from power cuts and surges. For a NAS, this is not optional — losing power during a write operation can corrupt data and damage drives.
| Model | Capacity | Runtime (NAS) | USB/Network | Price |
|---|---|---|---|---|
| APC Back-UPS BE425M | 425VA | ~10 min | USB | ~£55 |
| APC Back-UPS BX750MI | 750VA | ~20 min | USB | ~£85 |
| CyberPower VP1000ELCD | 1000VA | ~25 min | USB | ~£95 |
| APC Smart-UPS SMT750I | 750VA | ~20 min | USB + Network | ~£250 |
Key feature: USB connectivity lets the NAS detect a power failure and shut down gracefully before the battery runs out. Synology and QNAP both support this natively.
Cables and Accessories
Small things that make a big difference:
- Ethernet cables — Cat6 for new installs (futureproofed for 10GbE), Cat5e is fine for 1GbE
- Patch panel — If you're running more than 4 cables, a patch panel keeps things sane
- Labelling — A label maker (Brother P-Touch) is the most underrated tool in any setup
- Cable management — Velcro ties, not zip ties (things change)
- Temperature monitoring — A cheap USB thermometer in your server cupboard
Building vs Buying
Buy a NAS if:
- You want appliance-level simplicity
- You value a polished web UI
- You're running file storage + light Docker loads
- You don't want to think about hardware compatibility
Build your own if:
- You need more CPU/RAM than pre-built NAS offers
- You want to run VMs alongside containers
- You want ECC RAM, specific NICs, or unusual configurations
- You enjoy building things (the adze.uk audience, presumably)
A popular DIY approach: old enterprise micro PC (Dell OptiPlex, Lenovo ThinkCentre) + TrueNAS or Unraid. Often £100–150 for a machine that outperforms a £400 NAS in raw compute.
