Updated October 2026. Picks are based on published specs and reliability that owners report. I haven't tested every unit, and I point out the trade-offs.

Hosting a game server for you and your friends is one of the most fun home lab projects, and it means no monthly hosting bill. The hardware math surprises people: most game servers, Minecraft especially, depend on how fast a single core is, not how many cores you have.

A chip with fast individual cores and enough RAM beats a many-core server chip with slower cores. Here's how to pick based on how big your world is and how many people play.

Words you'll see in this guide
  • Cores: the separate workers inside a processor. More cores means more jobs at once.
  • Single-core speed: how fast one core works on its own. This is what keeps a Minecraft world from lagging.
  • RAM: your computer's main working memory. More RAM lets it run more apps at once. AI models can run from it too, just slower than from VRAM.
  • Tick: one update of the game world. Minecraft aims for 20 per second, and lag starts when the server can't keep up.
  • Off-lease: business computers returned after a few years and resold used, usually cheaply.
  • Docker: a tool that runs each app in its own sealed box, so apps don't break each other or your system.

What matters for a game server

My top 3 picks

1
Used business tiny PC
Best budget: a few friends

Used business tiny PC (i5-8500T class)

A six-core off-lease ThinkCentre M720q, OptiPlex, or EliteDesk has plenty of single-core speed for a small Minecraft server, Valheim, or a Terraria world with a handful of players.

  • Upgrade: take the RAM to 16 GB and it handles more than you'd expect.
  • Power: low enough to leave on around the clock.

This is where I'd start. See the used tiny PC guide.

2
N305 mini PC
Best all-rounder

Intel N305 mini PC (8-core, 32 GB)

If the game server shares a box with your other services, an N305 mini PC with 32 GB has room for a modded Minecraft or Palworld world plus a media server and other apps at the same time.

  • The limit: its single-core speed is modest. It suits medium worlds better than a big modded server with lots of players.
  • Pick it if: you want one do-everything home box that also hosts games.

3
Small-form-factor desktop
For big modded servers and many players

A modern small desktop (fast Ryzen or Intel)

Run a large mod pack or a full server of players and single-core speed becomes the bottleneck. A current desktop chip with a high clock speed pulls well ahead of any low-power mini PC here. A recent Ryzen or Intel Core with 32 GB of fast RAM and an SSD handles the heaviest Minecraft worlds.

  • Not for you if: your world is small. It's overkill until the smaller boxes start to lag.
  • Watch the power: it runs all day, every day. Here's how to estimate the cost.

Also worth considering

The tightest budget, if your world and player count are small.

Rough sizing by game

Game and worldRAM to budgetWhat it needs
Minecraft, small and unmodded (2 to 8 players)4 to 8 GBAny used tiny PC with Paper
Minecraft, modded or a bigger group8 to 16 GBFast single core plus RAM
Valheim (small group)8 GBA used tiny PC is fine
Palworld (dedicated server)16 GB or moreUses lots of RAM, so plan generously

Prices change constantly, so I link to current listings instead of quoting numbers that go out of date.

Run each game server in a container or virtual machine. With each game in its own Docker container or Proxmox virtual machine, you can back up a world, update a mod pack, or delete one without touching anything else. It also makes running two game servers side by side easy. See Docker vs Proxmox.
