Computer Guy's Mod
Computer Guy's Mod adds weapons, decorative computers, rats and mice to NeoForge worlds for 1.21.1, aimed at chaotic servers and players who want heavier weapons.
What it does
The mod places decorative computers into a world and adds weapons that can be built from crafted parts. Rats can be tamed with cheese, sat down with a right click, and given a sword to hold in the same way. Mice and extra rats are added as further creatures that fill out the same theme.
Each new item and creature is meant for play on a shared world, where weapons and pets can change how a server develops. Because the mod runs on client and server, every player who joins a server running it needs it too.

Key features
Decorative computers
Computer blocks are placed as decoration, giving builds a retro-tech look without any gameplay function.
Weapon crafting
Weapons are built from crafting recipes and can be used against other players and mobs on a server.
Taming rats
Rats are tamed with cheese, and a tamed rat can be made to sit with a right click.
Lore and additions
The mod adds lore items and mice to the world, so exploration turns up new content beyond the weapons and computers.

Use cases
Chaotic servers
Server owners who run open-ended, PvP-heavy worlds can use the weapons to shift the balance between players.
Decorative builds
Builders can place the computer blocks to furnish rooms or themed areas.
Who it’s for: The mod suits players who enjoy computer themes and weapon combat, and server communities that accept rough, unbalanced play. The author describes it as a small personal project, so it may not suit those who expect steady balance changes.
How it compares
Ratmetal is a NeoForge mod for 1.21.1, also client and server, and under All rights reserved like Computer Guy's Mod, so it is not open source. Rats is open source under the GNU Lesser General Public License v3.0 only, with NeoForge and Forge files for 1.12.2 – 1.20.1, so its version range does not reach 1.21.1.
