In the rack
Last verified: 2026-04-21
The kit currently running the house, the theatre, and the lab. Public list — some of the sharper edges (personal devices, keys, tokens) are deliberately not on this page.
Cerberus
Unraid server. ASRock Z390 Extreme4, i7-8700K, 78 GB RAM, RTX 2060. Wired into VLAN 30 at 192.168.30.10.
The array is 7 disks — one parity, six data. Raw capacity 88 TB, currently 70.8 TB used with 17.2 TB free.

| Samsung 990 Pro | 4 TB NVMe | apps / system — 412 GB used |
| Toshiba MQ01ABD100 | 1 TB HDD | downloads — 443 GB used |
Boot is a 257 GB USB flash. Transcode ceiling is five concurrent Plex streams on the 2060 — enough that the family has never had to wait.
Oceanus
Synology 6-bay with a DX517 5-bay expansion bolted on. SHR with single-drive tolerance. 130.9 TB total, 108 TB allocated across volumes, 22.9 TB free at the pool level.

Volume 2 is the one to watch — 102.6 TB used, 1 TB free. On the shortlist for the next drive swap.
Its day job is receiving LuckyBackup app data from Cerberus and keeping a bidirectional sync of documents to Google Drive.
Networking
Two boxes do the work. Poseidon is a UDM Pro handling routing, firewall, and DHCP. Hermes is a Cisco Catalyst 2960-X doing the L2 switching.
Everything is Cat6 direct runs. No IPv6 — not for ideological reasons, just one fewer surface to maintain.
VLANs
01 · 10 · 20 · 30 · 40 · 50 · 60
VLAN IDs listed without role labels on purpose.
Cameras
Two IP cameras — front door and back door. Audio is wired on both. Faces are indexed locally on Frigate; nothing leaves the network.
Home Theatre
Theatre-first. Everything in this stack is picked for the room, not the rack.
- Epson EH-LS800 — ultra-short-throw laser projector
- Denon AVR-X4800H — 11.4-channel receiver
- Sofabaton X2 — universal remote, the glue that hides the complexity
- Nvidia Shield Pro — primary source
- Nintendo Switch 2 — second source
Motorised blinds are on the roadmap so the room can dim itself when a movie starts.
Smart Home
Less kit here than you might expect — most of the smart-home surface lives inside Home Assistant, not in hardware.
- Three Google Nest speakers — mostly used for announcements and TTS pipelines
- APC UPS — keeping the rack up through brownouts; battery is overdue for a physical swap
3D Printing
A Bambu Lab printer sitting outside Home Assistant for now — the HACS integration is on the list but not yet wired in.
[PLANNED]Planned
Enphase solar plus battery storage — the next big capital line item. The goal is enough on-roof generation to carry the rack through a daytime outage without touching the UPS.
