Thelio is designed to maximize the performance of every high-end component while remaining incredibly compact. Oversized fans quietly pull in cool air. Heat pipes rapidly draw heat from the CPU. Ducts contain the heated air and direct it out of the system. And a custom chassis controller coordinates and optimizes the flow.

Tinker to your heart’s desire. Thelio systems are created for you to customize with ease. Slip in drives, add memory, upgrade graphics cards. Add your own personal touch and make your computer feel like it’s really, truly yours.

Every design element was crafted with intention. Etched-in artwork and rounded corners create an inviting and professional aesthetic that’s open, friendly, and warm. Real walnut or maple wood compliment Thelio’s deep matte black finish. Care was taken to ensure you’ll feel proud to have this desktop sitting on your desk, not underneath.

*Rear ports differ by platform and options. See tech specs for port details.

Thelio IO board

Thelio Io is a System76 designed chassis controller and hard drive backplane that moves proprietary functionality from the mainboard to the open source Thelio Io daughterboard.

Moving chassis and thermal control to Thelio Io enables far more granular performance optimization. Motherboard data, fan speed, and GPU and OS data are used to coordinate optimal airflow.

Thelio Massive also includes an open source System76 designed SAS backplane for high performance 2.5” PCIe storage.

Unleash with tux

Thelio, Thelio Major, Thelio Massive, and Thelio Io are OSHWA certified open source hardware.

Licensed under GPL v3 and CC-BY-SA, everyone can learn from what we've created, adapt it, improve it, and make derivative works inspired by the Thelio design. We hope Thelio can be a spark for open source hardware, just as GNU and Linux were the sparks that forever changed the way software was developed and shared nearly three decades ago. Thelio and Thelio Io design files are hosted on GitHub.

US-sourced wood and aluminum are formed, finished, etched, and built by artisans in our Denver, Colorado factory. Premium components from around the world are then assembled to your final specifications. And to offset environmental impact, every Thelio sold plants a tree with the National Forest Foundation.

We back Thelio with a 30-day money back guarantee, lifetime technical support, free two-year hardware warranty, and rapid software updates.
