Summary
$200 in savings and up to 81% higher gaming benchmark performance put a custom Mini-ITX Steam Machine ahead of Valve’s official model in ETA Prime’s build test.
An AMD Radeon RX 9600 XT, Intel Core Ultra 5 250K Plus, 32 GB of DDR5 RAM and a 1 TB Kingston NVMe SSD drove 1440p and 4K gameplay at high or ultra settings.
Cyberpunk 2077, Spider-Man 2, Horizon Zero Dawn Remastered, Forza Horizon 6 and Mortal Kombat 1 all ran smoothly, while a 240 mm AIO cooler kept CPU temperatures below 57C.
The Mini-ITX system is slightly larger than Valve’s design, but its modular layout and SteamOS compatibility leave room for future GPU, RAM and storage upgrades.
The build’s pitch is long-term value: use sale-priced, price-to-performance parts now, or swap in older CPUs, DDR4 or mid-range GPUs to cut costs further.
