Ebook / audiobook library: hardware requirements guide
Self-hosted books and audiobooks (Calibre, Audiobookshelf, Kavita).
Hardware requirements by tier
Three tiers for every workload: the minimum that works, the recommended sweet spot, and the comfortable headroom level. These are the same tiers the WisePC decision engine uses when it plans a build around your goal.
| Tier | CPU cores | RAM | Storage | GPU | Network |
|---|---|---|---|---|---|
| Minimum | 1 cores | 2 GB | 1 TB (hdd) | None | 1 GbE |
| Recommended | 2 cores | 4 GB | 4 TB (hdd) | None | 1 GbE |
| Comfortable | 4 cores | 8 GB | 16 TB (hdd) | None | 1 GbE |
Which tier do you need?
- Pick Minimum (1 cores, 2 GB RAM) only for a single-purpose machine on a tight budget — expect little headroom.
- Recommended (2 cores, 4 GB RAM) is the sweet spot: enough for the workload plus the usual side-services, without overspending.
- Pick Comfortable (4 cores, 8 GB RAM) when this workload shares the machine with others or will grow — you pay for headroom, not for anxiety.
- GPU rule for this workload: None.
