Welcome to Thelio

The Thelio desktop line was born from the belief that humans are capable of anything. We believed that we could make an open hardware desktop that’s powerful, compact, quiet, beautiful, upgradable, backed by lifetime support, and manufactured in the United States—so we did. What will you make with it?

Out-of-this-world handcrafted systems.

Crafted With Intention in Denver, Colorado


US-sourced materials, US-based expertise

Thelio desktops are designed, engineered, and manufactured at our factory in Denver, CO using aluminum and wood sourced from US companies. For every Thelio purchased, we plant a tree through the National Forest Foundation.

Aluminum origins

Thelio begins as a solid sheet of aluminum. This is fed into a CNC laser-punch machine, where it’s cut, formed, and threaded.

Parts take shape

Chassis parts are cut and bent to precise measurements, ensuring each machine ships with the same high-quality construction.

Infused with elegance

Shimmering black powder coats the aluminum with a premium cosmic aesthetic. Every design choice embodies the character of our company and community.

Terrestrial wood veneer

Real walnut or birch wood is brushed with linseed oil and mounted to the chassis. Color options also include Neptune Blue, Martian Red, and Dark Matter stained birch.

Custom components

Assembly technicians combine parts and equip the latest, most powerful components as designed by the user.

Handled with care

Lastly, your system is delicately packaged for interstellar transit. Fully assembled Thelio desktops ship to US and Canada, with more locations to come!

Our products are constantly evolving. Customer feedback and thorough testing help us craft a faster, quieter, and longer-lasting system. Each iteration addresses the needs of our users while streamlining processes. And because we manufacture in-house, any changes we make can be applied to our production process as soon as they’ve passed testing.

Thelio Io is a System76-designed chassis controller and hard drive backplane that regulates Thelio’s thermals for consistent performance output. It does this using motherboard data, fan speed, GPU data, and OS data to coordinate optimal airflow and acoustics.


Making hardware that’s open source allows anyone to learn from the Thelio design, adapt it, improve it, and make derivative works inspired by what we've created. Thelio desktops and Thelio Io are all OSHWA-certified open source hardware licensed under GPL v3 and CC-BY-SA, with design files hosted on GitHub. 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.

System76 supports every user’s right to repair. In fact, the chassis is designed for it. When you buy a Thelio from us, it’s yours to customize, upgrade, tinker, and replace parts at will. We back this promise with lifetime support for your product and a 30-day money back guarantee.
