Everything is “free today” if you use old hardware and open-source software.
A first home server does not need to be a rack, does not need to be new, and does not need to cost more than $150. This is the absolute beginner walk-through: what a home server is, whether you actually need one, and how to build your first project this weekend with hardware you probably already have or can find cheaply.

What is a home server, really?
A home server is any computer in your home that provides a service to other devices on your network – and typically runs 24/7. That is it. It does not need to be in a rack. It does not need to look “serious”. It does not need to be new.
Common services a home server provides: file storage (photos, documents, backups), media streaming (Plex/Jellyfin for movies and TV), home automation (Home Assistant), network-wide ad blocking (Pi-hole or AdGuard Home), password manager (Vaultwarden), personal cloud storage (Nextcloud), photo backup from phones (Immich).
Do you actually need a home server?
Honestly, most people do not. Cloud services (Google Drive, iCloud, Netflix, Ring cameras) work fine for the majority of use cases. Home servers are for people who value privacy, want to escape subscription fees, enjoy tinkering, or have a specific workload that cloud services do not handle well.
Good reasons to build one: your family photo library is bigger than free cloud tiers and you refuse to pay $10/month forever, you want ad blocking on every device without installing apps everywhere, you want to run Home Assistant with local processing, you have a project idea that needs 24/7 uptime.
Bad reasons to build one: “It sounds cool” (it is, but you will have to maintain it). “It will save money” (usually true over 3-5 years, but the setup time cost is real). “I want to learn Linux” (fair – just do not build it as your primary tool if you also need it to work reliably from day one).
Cheap hardware options for your first home server
Any old laptop or desktop from the last 8 years works. Retire your old work laptop, install Ubuntu Server or Debian, done. Old ThinkPads are especially loved by this community for their reliability and low power draw.
If buying: refurbished Dell OptiPlex Micro or HP EliteDesk Mini units from ~2018-2020 are $80-150 on eBay and use 15-30W idle. New Intel N100 mini PCs (Beelink, GMKtec, etc.) are $180-220 and slightly faster.
Raspberry Pi 5 is fine for lightweight tasks but not great as a general-purpose home server. It struggles with media transcoding, NAS use, and anything I/O-heavy. Recommend only for narrow-purpose projects.
- Beelink Mini S12 Pro N100 Mini PC 16GB — New mini PC for first-time home server.
- Refurbished Dell OptiPlex 3070 Micro — Best used-hardware value.
- Raspberry Pi 5 8GB Kit — Pi option for narrow projects only.
- CyberPower CP1500PFCLCD UPS — UPS is important – unexpected power loss corrupts SSDs.
Free operating systems worth knowing
Ubuntu Server LTS – most forgiving for beginners. Well-documented, huge community, most Docker guides assume Ubuntu. Best default choice.
Debian – lighter than Ubuntu, more conservative updates. Slightly steeper learning curve but rock-solid.
Proxmox VE – free hypervisor if you want to run multiple VMs on one physical machine. Great when you outgrow “one thing per box.”
TrueNAS Scale – if storage is your primary need and you have 3+ drives.
CasaOS or Cosmos-Cloud – opinionated app-store experiences that hide most of Linux. Not what long-term home lab folks use, but great for absolute beginners who want to see something working today.
First projects worth building this weekend
Pi-hole ad blocker – runs on any old computer, blocks ads at the DNS level for every device on your network. Highest value-to-effort ratio of any home server project.
Immich (self-hosted Google Photos) – back up your phone photos to your own server. Face recognition, timeline view, and mobile app included.
Home Assistant – if you have any smart home devices, running Home Assistant locally beats any cloud alternative. Steeper learning curve but big long-term payoff.
Jellyfin or Plex – your own Netflix, from your existing movie library.
