Most workstations take up space, generate noise, and test your patience. The Thelio Major gives you back all three. Redesigned from the ground up, it's 13% smaller than its predecessor, runs 19% cooler, and delivers 7% more sustained CPU speed — so the performance on the spec sheet is the performance you get at hour six, not just the first five minutes. Built in Denver, engineered for Linux, and designed to outlast your workload.
