DeskPi RackMate TT Showcase Entry: A High-Density “Swiss Army Knife” Desktop Rack

By Christian Morton

Christian Morton’s DeskPi RackMate TT Showcase build is all about high-density hardware integration. Using the DeskPi RackMate TT as the foundation, this compact desktop rack brings together Apple Silicon, x86 virtualization, and specialized ARM networking—creating a powerful hybrid environment in a small footprint.

The Build Configuration

To fit such a diverse stack into the RackMate TT, Christian designed a series of custom 3D-printed mounts, ensuring every millimeter of space is used efficiently while keeping the layout clean and secure.

Hardware Layout

The Foundation

At the bottom of the rack sits an M4 Mac mini : https://print.deskpi.com/models/106, secured in a bespoke 3D-printed mount.

Virtualization Core

Next is an Intel NUC running Proxmox, hosting Zima and HAOS. It’s paired with an Offcom USB-C hub, and both components are held in place using custom 3D-printed mounts.

The Pi Shelf

On the central shelf, two systems are mounted side by side:

  • A Raspberry Pi 5
  • A Raspberry Pi CM5 on a Waveshare Mini Base Board B, running OpenWrt

Specialized Networking

Connected to the CM5 is an ALFA Wi-Fi adapter, mounted using a custom bracket that reuses the RackMate’s handle hardware for a clean, factory-style finish. A dedicated mount was also created for the external Wi-Fi antenna, positioned on the back-left corner of the rack.

Smart Home

At the top of the rack, a Philips Hue Bridge is integrated using a custom 3D-printed bracket.

Future Roadmap

Two upgrades are currently being finalized to complete the “Swiss Army Knife” rack:

  • Integrating a TP-Link TL-SG1005P 5-Port PoE Switch into the final empty top slot
  • Adding a PoE HAT to the Raspberry Pi 5 to further optimize power management

Closing Thoughts

The RackMate TT proved to be the perfect chassis for this project. By combining the included shelving with custom 3D-printed components, Christian was able to build a truly one-of-a-kind desktop lab—compact, organized, and ready for future expansion
