(Image credit: Meta PCs) Meta PCs has announced preorders for Steamroller , the first prebuilt gaming PC running on SteamOS. The system features standard PC components that are broadly similar to those offered by Valve in the base variant of the Steam Machine . Priced at $1,299, the Steamroller is available for preorder now, with shipping set to begin on July 3, 2026. Buyers can also opt for an extended warranty, with two-year and three-year plans available for $180 and $240, respectively. The Steamroller uses the Jonsbo D32, a well-ventilated m-ATX chassis with an AMD Ryzen 9600X, which is a 6-core, 12-thread CPU capable of boosting up to 5.4 GHz. Meta PCs mentions that the B650M/B650M Wi-Fi m-ATX motherboard will vary in brand and styling, meaning not all Steamroller PCs are alike, though they shouldn’t vary in terms of performance. For graphics, the system comes with AMD’s last-gen Radeon RX 7600 based on the RDNA 3 architecture with 8GB of GDDR6 memory.…
