This is a reference hub and showcase for how I run, secure, and document my homelab and daily Linux workflows as well as solutions for problems I have faced (see troubleshooting section).
In 2025 I built my first PC ever from the ground up. Normally I am not a big fan of desktop PCs because they tend to take up much space, but I wanted something that I can expand in the future. At first I was looking for some kind of tower case with lots of bays like the THERMALTAKE Level 10 GT. But again my taste is too exotic, so I settled for the Newway NW1. Then in august 2025 I changed my mind again and wanted a smaller case, because I bought an old used Chieftec case I could expand with lots of HDDs and optical drives. I googled for weird and uncommon cases with unique features and immediately fell in love with the first result: the Jonsbo D31 mesh with screen.
For now I am really happy with this case. The builtin screen is perfect for docking messengers or monitoring software or as a backup if my primary monitors aren't working. Currently I have it configured to display btop as a wallpaper (via a KDE plugin).
AMD Ryzen 5 5600G - 6x 3.90 GHz AM4
For the GPU I went with the ASUS Dual Radeon RX 7600 EVO OC Edition 8GB GDDR6 which seemed like a decent middle tier graphics card. It runs even Silent Hill 2 remake pretty well on higher details. As long as you play on Linux of course. On windows the performance was expectedly much worse. It runs smaller LLMs, though not well. For the future I'm planning on getting a GPU with decent vRAM (16GB upwards) to really get good use out of local models.
- Motherboard: ASUS TUF Gaming B550M-PLUS WiFi II
- RAM: Patriot Memory Viper Elite II DDR4 2x32GB
- PSU: Toughpower Gt
- CPU cooler: Thermalright Assassin X 120R Digital Black
- Rear fan: Thermalright TL-S12
- USB PCIe 5 slot expansion card with power delivery
- more powerful GPU for better LLM inference and maybe gaming with raytracing
- Top fans, maybe AIO cooler
- CPU with more powerful iGPU
I have two RPis: a Raspberry Pi 3 which is currently not in use and a Raspberry Pi 4b 4GB which I currently use as a BlackArch-based security and lab node. I'm always having trouble finding good use cases, since I can do most stuff with my NAS already. I tried using it as a retro gaming station, but I hardly used it. So for now I have configured it as a server to experiment. I have WiFi antenna with monitor mode plugged in so I can practice a bit of pentesting. It also runs a snowflake proxy.
Case is the awesome GeeekPi Argon One V2 with M.2 expansion and a 240GB NVMe SSD.
I currently run Proxmox on Lenovo ThinkCentre M715q hardware for more demanding services that would otherwise consume too many resources on the NAS.
- Lenovo ThinkCentre M715q (AMD PRO A10-9700E)
- 16GB DDR4 RAM
- 1x 512GB NVMe SSD
- 1x 240GB SATA SSD
Current role:
- Hosts memory-intensive services (for example OPNsense and OpenWebUI)
- Runs LXC and containerized workloads depending on use case
- Serves as part of the core homelab compute layer
I previously used Synology devices (DS218j and DS224+), but recently moved my main workload to the Ugreen DXP2800. Main reasons were better hardware value for the price and more flexibility for splitting workloads across HDD and NVMe storage.
Configured Memory & Storage:
- 8GB DDR5 RAM
- 1x 4TB HDD
- 1x 2TB HDD
- 1x 2TB NVMe SSD
Current role:
- Main NAS and service host for always-on workloads
- Storage backend for documents, photos, and media
- Docker/LXC-adjacent services with backup integration into the wider homelab stack
Lenovo ThinkPad T570 — Intel i7-7600U, 16 GB RAM, 512 GB NVMe, running CachyOS (BORE+LTO kernel) with LUKS2 full-disk encryption and AppArmor.
Pixel 8 with GrapheneOS.
Pixel Tablet with GrapheneOS. Tried to use it as a laptop replacement. Not really useful for that, since it's media tablet with limited RAM and GrapheneOS and smart launcher seem to eat a lot of RAM.
FRITZ!Box 7590 AX v2 from my ISP. Will upgrade to one with OpenWRT support once I can afford it.
Everything sits behind the Fritzbox on the LAN subnet, with Zoraxy as the single reverse-proxy/TLS entry point for anything I expose. The two Proxmox nodes carry almost everything in the hosted services table below — PVE1 (ThinkCentre M630e) leans toward data/infra and misc utility LXCs, PVE2 (ThinkCentre M715q) toward identity, databases, and user-facing apps (Open WebUI, automation, dashboards) — with the NAS picking up media and always-on storage-adjacent services. The Raspberry Pi sits a bit outside that, running its own Tor Snowflake proxy and WiFi pentest lab. Anything remote — gaming PC, laptop, phone, tablet — reaches back in over Tailscale instead of poking holes in the router.
Mapped with Scanopy, a self-hosted network-discovery daemon I run here — it's systemd-managed now with a weekly scheduled scan, keeping this diagram honest against what's actually live instead of my memory of what I set up months ago.

The AI stack lives entirely on one LXC on PVE2 (hostname ai-hub — still shows up as openwebui in some of my older notes, need to fix that). Open WebUI is the front door; behind it sits Hermes, a small Python agent gateway I built to run scheduled cron jobs (it checks my job-application inbox every morning and updates a Notion tracker, for example) and uses Signal as its gateway/delivery channel. The Conduit Android app is the mobile client channel into Open WebUI. Anything the agent needs beyond raw chat — web search, code search, database access, container management, network discovery — comes through the mcpo bridge proxying six stdio MCP servers (sequential-thinking, firecrawl, notion, tavily, portainer, scanopy) plus MCPJungle, an MCP gateway fronting eleven upstream MCP servers (baikal, dbhub, homarr, homebox, karakeep, patchmon, portainer, protonmail, proxmox, reactive-resume, sure). Long-term memory across sessions is handled by Honcho's managed cloud offering. Inference comes from LM Studio — headless on the gaming PC for bigger models, plus a small always-on model on ai-hub via the official llmster daemon — with cloud models via xAI/Grok and OpenRouter routed through Hermes.
Diagram below is generated from the actual live service/port state on the box, not from what I remember configuring, so it should stay accurate as long as I keep re-deriving it instead of hand-editing.
