BEGINNER GUIDE
What is a home server, and do you actually need one?
A home server is simply a computer that provides useful services to other devices in your home. It might store photos, stream media, run automations, host a private cloud or provide a home for software you would otherwise use through somebody else's service.
It does not have to look like a server
A home server can be a mini PC, an old desktop, a NAS, a Raspberry Pi or another small computer that stays available when you need it. The right choice depends more on the workload than on the shape of the box.
What can you run on it?
- Photos: software such as Immich can organise a photo and video library.
- Files: services such as Nextcloud can provide file sync and collaboration.
- Media: Jellyfin can stream a personal film, TV and music library.
- Documents: Paperless-ngx can turn scanned paperwork into a searchable archive.
- Automation: Home Assistant and n8n can automate devices or digital workflows.
- AI: Open WebUI can provide an interface for local or remote AI models.
Why would you want one?
The strongest reasons are usually control, flexibility and learning. You decide where the files live, which software runs, when it is upgraded and how it is backed up. It can also reduce reliance on individual cloud services, although self-hosting is not automatically cheaper.
What do you take responsibility for?
The trade-off is that somebody has to maintain the system. Updates, failed disks, backups, security and recovery become your problem rather than a provider's. If losing the service would matter, plan how you would restore it before depending on it.
A sensible first rule
Choose one useful project before choosing hardware. A £100 mini PC that solves a real problem is a better first server than an expensive machine bought because it looks capable.
How much power does a home server use?
There is no single figure. A low-power mini PC at idle and a desktop with several hard drives are very different systems. Use actual wall-power measurements if possible, then put them into our home server electricity cost calculator.
Do you need one?
If you enjoy maintaining technology, want more control over particular services or have a clear job for an always-on computer, a home server can be worthwhile. If your priority is simply having a service that works without maintenance, a managed cloud service may be the better answer.
