Description
A compact, modular homelab rack designed for stacking mini PCs such as Lenovo ThinkCentre systems.
Inspired by a design by @RaidOwl_2908363, this build is tool-free and requires no screws or additional hardware, making it easy to assemble, reconfigure.
The rack can support multiple mini PC units and includes an empty expansion bay with a customizable front cover, allowing you to use it for usb storage or other accessories.
I made a custom front-panel that integrates a LILYGO TTGO ESP32 display module, showing some basic status of my machines.
I've added some blank plates for you to customize.
