The new Thelio Mira is designed to accommodate high-end Nvidia GPUs, including the recently released GeForce RTX 5090.
The chassis has undergone a notable redesign, departing from the original wood veneer look toward a style System76 calls “Precision Industrialism.”
This update provides easier access to front panel I/O, improves airflow, with an approximate 13.5-degree reduction in heat, and enhances repairability.
The new Thelio Mira delivers performance gains through thermal and architectural improvements.
Its CPU clock speeds have increased by up to 19%, while liquid cooling allows the processor to sustain peak performance during extended, compute-intensive tasks.
A removable bottom dust filter also helps the device maintain airflow and long-term performance.
Internally, the layout supports large GPUs up to 358mm in length, and the primary PCIe 5.0 x16 slot accommodates cards up to four slots in height.
