A compact DIY gaming PC built for under $170 is drawing attention because it delivers far more than a bargain-bin experience. Using second-hand parts, a small case, and Batocera OS, the setup aims to handle both modern games and classic emulation in a single box.
The appeal is not just the low price. The build is designed as a practical mini Steam Machine-style system for players who want a small, portable device that can still run demanding titles and older console libraries.
What the build includes
Spec Tech puts the total cost at around $166 by pairing a used Intel Core i5-2500 priced at $9 with an AMD Radeon RX 550 priced at $36. The system also uses 16GB of DDR3 RAM for $24 and a 240GB SATA SSD for $23 to keep the machine responsive.
The remaining hardware is chosen to fit a tight ITX layout. A Metal Fish T40 case costs $22, a B75 ITX motherboard costs $27, and a salvaged SFX 550W PSU can be free or about $10.
Because the enclosure is so compact, the build also needs a $15 PCIe riser cable for the graphics card. A $10 USB Bluetooth dongle is included as well, giving the system easy wireless controller support.
Why Batocera OS matters
Instead of a conventional desktop operating system, the machine runs Batocera OS. The Linux-based platform is built specifically for gaming and is known for staying light on older hardware.
Its interface is said to feel similar to Steam OS, which helps the system behave more like a console than a regular PC. That approach is useful for users who want a simple living-room gaming setup with minimal configuration.
Batocera OS also supports EmuDeck integration for emulation. That makes it easier to place retro titles, including PlayStation 1 games, into the same front-end as modern PC games.
AMD driver support built into the platform is another advantage for this configuration. It helps the Radeon RX 550 work smoothly in both gaming and emulation use cases.
Performance across modern and retro titles
Despite the modest budget, the system reportedly delivers strong results in several games. Silk Song, an indie title, is said to exceed 200 FPS at 1080p.
More demanding games are also within reach. Tomb Raider reportedly runs at 50 to 70 FPS on high settings, while CS: GO reaches around 50 to 80 FPS on low settings and 50 to 70 FPS on medium.
The Witcher 3 is also playable on the machine. It is reported to reach 30 to 40 FPS on low settings, showing that the build can still handle an older but heavier RPG at a workable frame rate.
A budget build focused on function
The project is less about luxury and more about squeezing the most out of every dollar. Used components and a salvaged power supply are central to keeping the total price low without abandoning gaming performance.
Bluetooth support adds another practical advantage by making wireless controllers easier to use. That turns the compact PC into something that can function much like a home console while still offering the flexibility of a computer.
With a small footprint, emulation support, and enough power for a range of modern and retro games, the build shows why a cheap Steam Machine-style PC remains realistic. For users working with limited space and a limited budget, it offers an unusually balanced combination of portability, value, and versatility.
