What is a Home Server?

You’ve probably heard the term “home server” thrown around in tech circles, but what does it actually mean? And more importantly, is it something you should bother with? Let’s break it all down.

Clients and servers — what’s the difference?

Before we get into home servers, it helps to understand two fundamental concepts: clients and servers.

A client is any device that requests information or services. Your phone, your laptop, and your tablet are all clients. When you open a website, your browser (the client) sends a request to another computer somewhere, asking for the page.

A server is the computer that responds to those requests. It “serves” data to the clients that ask for it. When you stream a film on Netflix, Netflix’s servers send the video data to your device. When you upload a photo to iCloud, Apple’s servers store it for you.

Here’s the thing though — a server doesn’t have to be some massive machine in a data centre. A server is just a computer that provides a service. That old laptop gathering dust in your cupboard? It could be a server. And that’s essentially what a home server is: a computer in your home that runs services for you and your household, on your terms.

Why would you want a home server?

There are loads of reasons, but here are the big ones:

  • Privacy and ownership. Your files, your photos, your data — stored on hardware you own, not rented cloud space controlled by a corporation. No one’s scanning your files or training AI models on your photos.
  • No subscription fees. Instead of paying monthly for cloud storage, media streaming, or file sharing services, you pay once for the hardware and run open-source software for free.
  • Learning. Running a home server teaches you about Linux, networking, Docker, and system administration — genuinely useful skills whether you’re in tech or not.
  • Customisation. You get to decide exactly what services you run, how they’re configured, and who has access.
  • It’s fun. Seriously. There’s something deeply satisfying about hosting your own stuff.

Common things people run on home servers include media servers (like Jellyfin or Plex), photo backup solutions (like Immich), file clouds (like Nextcloud), game servers, ad blockers (like Pi-hole or AdGuard Home), password managers (like Vaultwarden), and much more.

How to set up a home server

There’s no single “right” way to do this. Your setup depends on your budget, your goals, and how deep you want to go. Here are the main routes:

Option 1: Buy a pre-built NAS appliance

Products like Synology, QNAP, and Umbrel Home are designed specifically for this. They come with their own operating systems, app stores, and web-based management interfaces. You plug them in, follow the setup wizard, and you’re off.

Pros: Dead simple to set up. Great for people who just want something that works out of the box. Cons: More expensive per unit of performance. You’re often locked into the manufacturer’s ecosystem and software. Upgradeability is limited.

Option 2: Repurpose a spare PC

Got an old desktop or laptop sitting around? Stick Linux on it. This is the cheapest way to get started and it’s genuinely capable. Old office PCs — especially small form factor machines or towers from the likes of Dell, HP, and Lenovo — are brilliant for this. You can find them on eBay for next to nothing.

Pros: Extremely cheap (potentially free if you’ve got something lying around). Good enough for most lightweight services. Cons: Older hardware might be power-hungry relative to performance. Limited expandability depending on the machine.

Option 3: Build your own

This is the most flexible option. You pick every component, so you get exactly what you need — no more, no less. It’s also the most fun if you enjoy tinkering.

Pros: Fully customisable. You can upgrade individual parts over time. Best performance-per-pound in the long run. Cons: Requires more research upfront. You’re responsible for compatibility and assembly.

The best setup for absolute beginners (custom build)

If you want to go the custom-build route but don’t know where to start, here’s a sensible foundation:

Storage: NAS hard drives in RAID 1

This is the most important part. Get at least two NAS hard drives of the same size and set them up in RAID 1 (also called a mirror).

What does RAID 1 mean? It means both drives contain an identical copy of your data at all times. If one drive fails, your data is still safe on the other. You simply replace the failed drive, the array rebuilds, and you carry on as normal. It’s not a backup (you should still keep off-site backups), but it protects you against hardware failure, which is the most common way people lose data.

Why NAS drives specifically? Drives marketed as “NAS” drives (like the Western Digital Red Plus or Seagate IronWolf series) are engineered for the kind of workload a server puts on them: running 24/7, handling constant read/write operations, and vibrating alongside other drives in an enclosure. They’re built to last longer under these conditions and typically come with better warranties. Standard desktop drives will work if you’re just experimenting, but for anything you care about long-term, NAS drives are the way to go.

Memory: Get enough RAM, and consider ECC

RAM matters more on a server than you might think. Every service you run consumes memory, and if you’re running a handful of Docker containers, things add up. 16GB is a solid starting point; 32GB gives you comfortable headroom.

If data integrity is especially important to you, look into ECC (Error-Correcting Code) RAM. ECC memory can detect and correct single-bit errors before they cause problems. For most hobbyists, standard RAM is perfectly fine — but if you’re storing irreplaceable data or running services around the clock, ECC offers that extra layer of confidence. Just make sure your motherboard and CPU support it.

GPU: Only if you need it

Most home servers don’t need a dedicated graphics card at all. The exception is if you plan to run a media server that needs to transcode video on the fly (converting a 4K file into a lower resolution for a device that can’t handle it), or if you’re using your server as an editing workstation or for any kind of GPU-accelerated processing. In those cases, even a modest NVIDIA card with hardware encoding support (NVENC) can make a huge difference. Intel CPUs with Quick Sync are also great for transcoding without needing a dedicated GPU at all.

Operating system: TrueNAS SCALE

For a custom build, we’d recommend TrueNAS SCALE. It’s a free, open-source operating system purpose-built for NAS and server use. It gives you:

  • A clean, easy-to-use web UI for managing your server from any device.
  • ZFS under the hood — one of the most robust and reliable file systems available, with built-in data integrity checks, snapshots, and RAID-like redundancy.
  • A Docker-based apps experience that lets you install and run services with just a few clicks. Jellyfin, Immich, Nextcloud, Vaultwarden — all installable from TrueNAS’s app catalogue.

It’s a fantastic choice for beginners who want the power of a custom server without having to live in the terminal.

UPS: Not essential on day one, but worth planning for

A UPS (Uninterruptible Power Supply) is essentially a battery backup for your server. If the power goes out, the UPS keeps your server running long enough to shut down gracefully, preventing data corruption or file system damage.

You don’t need one right away, but once your server becomes something you rely on daily, a UPS is a wise investment. You can pick up a decent one from APC or CyberPower without breaking the bank.

Networking: Use Ethernet, not Wi-Fi

This one’s straightforward — plug your server into your router with an Ethernet cable. Wi-Fi is fine for laptops and phones, but a server needs a stable, low-latency connection that doesn’t drop out when your microwave turns on. Ethernet gives you that reliability.

Most motherboards come with a 1Gbps NIC (Network Interface Card) built in, which is more than enough for most basic home server needs — streaming media, syncing photos, serving files, and running game servers all sit comfortably within that bandwidth. If you find yourself needing more down the line (say, multiple users hammering the server with large file transfers simultaneously), you can always upgrade to a 2.5Gbps or 10Gbps NIC with an add-in card, but for the vast majority of people, the onboard 1Gbps port will do the job just fine.

Making your server accessible remotely

Once your server is up and running at home, you’ll probably want to access your services from outside your local network — on your phone whilst you’re out, from a friend’s house, and so on. There are a few ways to do this:

  • Cloudflare Tunnels are one of the easiest and most secure options. They let you expose your services to the internet without opening any ports on your router, which is a big deal from a security standpoint. Setup is straightforward and Cloudflare’s free tier is very generous.
  • Tailscale creates a private, encrypted network (a “tailnet”) between your devices. It’s not publicly accessible — only your authorised devices can see your server. Brilliant for personal use.
  • Reverse proxies like NGINX or Caddy give you more control if you do want to open ports, letting you route traffic to different services based on domain names and handle SSL certificates.

Running DDD projects on your home server

If you’re setting up a home server, a couple of our projects might come in handy:

Craftbox — manage Minecraft servers from your browser

If you or your mates play Minecraft, Craftbox lets you create, configure, and manage Minecraft servers from a web panel — no command-line fiddling required. It supports Vanilla, Paper, Purpur, Fabric, Forge, NeoForge and more, with a live console, one-click backups, plugin/mod management, crash detection, and auto-restart. It runs in Docker, so spinning it up on TrueNAS SCALE is a breeze.

Dropgate — private, encrypted file sharing

Dropgate is a self-hosted, privacy-first file sharing system. Upload a file, get a link, share it — and the file is end-to-end encrypted so even the server can’t read it. It also supports direct peer-to-peer transfers when you want to skip server storage entirely. If you’ve ever wanted your own private alternative to WeTransfer or Google Drive sharing links, Dropgate is exactly that. Pair it with a Cloudflare Tunnel and you’ve got secure file sharing accessible from anywhere.

A few extra tips

  • Start small. You don’t need to spend a fortune on day one. Get something running, learn the ropes, and upgrade as your needs grow.
  • Keep things updated. Regularly update your OS, Docker containers, and applications. Security patches matter, especially if any of your services are internet-facing.
  • Set up monitoring. Tools like Uptime Kuma (for service uptime monitoring) and Netdata or Grafana (for system resource monitoring) help you keep an eye on things without constantly checking manually.
  • Backups, backups, backups. RAID is not a backup. If your house floods or your server gets stolen, RAID won’t save you. Use something like rsync, Restic, or a cloud backup provider to keep an off-site copy of anything you can’t afford to lose.
  • Document your setup. Future you will thank present you. Keep notes on what you’ve installed, how you’ve configured things, and any quirks you’ve run into. A simple Markdown file or a wiki (you can even self-host one!) goes a long way.
  • Join a community. Subreddits like r/homelab and r/selfhosted are goldmines of advice, inspiration, and troubleshooting help.

A personal note from WillTDA (Founder of Diamond Digital Development)

“I started getting into homelabbing after I left college in June 2025. I started off with a Dell Optiplex T1700 Mid Tower I found on eBay, and scraped together about £350 to buy 2x12TB NAS Hard Drives. Even with a 2013 office PC, I was able to comfortably run a Jellyfin media server (1080p H.265 streams), Minecraft servers, run an iCloud Photos replacement (Immich + iCloudPD), and even my own private file cloud (I’ve upgraded my server to a custom-built solution since then!). You’d be surprised how good Linux is with resource management. To make everything accessible to my devices anywhere I go, I like using Cloudflare Tunnels. Super easy to set up, would highly recommend it if you wanna go the extra mile. Running a home server has helped me to better understand Linux too, as well as why Docker is super useful in DevOps.”

Should you have a home server?

If you value your privacy, want to stop paying monthly subscriptions for things you could host yourself, or simply enjoy learning how things work — yes, absolutely. The barrier to entry has never been lower. Open-source software has matured to the point where you can have a fully functional, self-hosted setup running in an afternoon, even if you’ve never touched a command line before.

Your data, your hardware, your rules. That’s the whole point.
