Introduction

As I have mentioned in previous posts, a HomeLab does not require thousands of dollars in rack servers or industrial hardware to be robust and highly functional. With a bit of skill, second-hand parts, and stable operating systems, we can build a great infrastructure at home.

This entry serves as a unified control panel and spec sheet for my entire lab. Here you will find the detailed hardware specs of each machine, the updated logical network diagram, and an interactive catalog with a built-in search filter to explore the services I have running in real-time.

If you want to see the step-by-step details of how I configured the parts of this network, here are the links to the full series:

Hardware Specifications

Currently, my lab is composed of two main physical nodes. Each serves a different and complementary role: the Raspberry Pi 4B acts as the node for essential services and low-power local networking, while the HP Elitedesk 705 G3 (bought on Wallapop and upgraded with extra storage) handles the services with higher read, write, and multimedia computing demands.

Interactive Logical Network Diagram

This logical diagram represents the connections in the lab. All incoming external traffic accesses securely through the Cloudflared Tunnel and is routed to the Nginx Proxy Manager, which filters and redirects internal requests to the corresponding node and port.

Active Catalog of Self-Hosted Services

All services in the lab run isolated using Docker containers. Below I show the list of active services, specifying the physical node where they run, their internal/external visibility status, and their corresponding technical descriptions.
