a premium price 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.

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.

Benchmarks and initial testing suggest the system handles demanding workloads effectively, running the Pop!_OS 24.04 operating system with the new COSMIC desktop environment.
The Thelio Mira supports a wide range of GPUs, from the RTX 5050 to the 5090, and includes the AMD Radeon RX 9070 XT as an option.
Storage options are extensive, with multiple PCIe NVMe generations supported, although some configurations disable secondary slots depending on occupancy.
Networking is provided through Wi-Fi 7, Bluetooth 5.2, and 2.5 Gigabit Ethernet, and audio outputs reach up to 7.1 channels via the Realtek ALC1220 codec.
Power requirements vary depending on the GPU, with certain configurations needing up to a 1000W PSU.
Despite the system's comprehensive specifications, attention has focused on the price of the RTX 5090 upgrade.
System76 is asking $5,299 for the GPU, a figure that exceeds the cost of most of the systems memory configurations, including 96GB of DDR5-5600 RAM, which retails for substantially less.
At the moment, you can get an entire PC with an RTX 5090 GPU for less than $5,100, showing the disparity between the GPU cost and the rest of the configuration.
This raises questions about the perceived value of such an upgrade for
typical Linux desktop users.
The rest of the Thelio Mira hardware, although high-end, can already handle most workloads without the top-tier Nvidia card, making the need for it questionable.
It remains to be seen whether the RTX 5090 upgrade will appeal beyond enthusiasts willing to pay a premium for a Linux-ready, ultra-high-end GPU solution.
