# Items Overview

Almost everything you mount, trade, or recycle in this **crypto mining simulator** is an item. Here’s the category map.

## Categories

| Category              | Role                                                           |
| --------------------- | -------------------------------------------------------------- |
| **Rig Frames**        | Placed on the bay grid; hold the build                         |
| **Motherboards**      | Required foundation; PCIe / slot capacity + small rarity bonus |
| **CPUs**              | Required; rarity can add hash bonus                            |
| **GPUs**              | Primary hash rate                                              |
| **Power Units (PSU)** | Must cover total GPU watt draw                                 |
| **Fans**              | All slots must be filled; rarity sets cooling bonus band       |
| **Cables**            | Required connection; rarity bonus band                         |
| **Consumables**       | Optional 24h boost; max **one** active per rig                 |
| **PCs**               | Prebuilt-style mining power items (when present in catalog)    |
| **Packs / vouchers**  | Open for randomized components (often untradable as packs)     |

## Operational rule of thumb

A rack earns only when the full checklist is met — see [Building Mining Rigs](/rig-rooms-docs/play-and-earn/building-mining-rigs.md).

## Rarity

Common → Uncommon → Rare → Ultra Rare → Legendary. Details: [GPU Tier Rarities](/rig-rooms-docs/game-systems/gpu-tier-rarities.md).

## Condition

Mint parts trade and burn cleanly. Worn parts lose output; Fried parts go to [Recycle Bin](/rig-rooms-docs/game-systems/recycle-bin.md). Details: [Condition & Repair](/rig-rooms-docs/game-systems/condition-and-repair.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://rig-rooms.gitbook.io/rig-rooms-docs/game-systems/items-overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
