Steam Machine with custom covers, but not all will be on sale

Valve’s new Steam Machine is a compact living room PC built around SteamOS, a 6-core Zen 4 CPU, and a semi-custom RDNA3 GPU with 28 compute units. It targets console-class 4K gaming with upscaling, using 16 GB of DDR5-5600 memory, 8 GB of GDDR6 VRAM, and 512 GB to 2 TB of storage plus a microSD slot that can share libraries with Steam Deck.
The design started from the thermal layout and then moved outward to the cube-style enclosure. A single custom 120 mm fan cools the CPU, GPU, and 300 W internal PSU, pulling air from the bottom and side vents and exhausting it at the back. Valve says the case keeps most of its airflow as long as it is not sitting directly on carpet.

The front of the system is built around a magnetic, tool-free faceplate. This began as a way to make dust cleaning easier by letting users pull off the mesh without opening the whole case. Once the feature was in place, Valve leaned into customization and shaped the front details to match the Steam Deck family while still fitting into typical living rooms.
Valve plans to release 3D files for the front covers so users can print their own versions. That includes options that favor airflow, different surface textures, or other visual tweaks, all using the same magnetic mounting system. The company expects builders and modders to treat the faceplate as the main visible modding area for the box.

Inside Valve, engineers have already experimented with more advanced covers. One internal prototype uses an E-ink panel on the front of the Steam Machine to display graphics (looks like its hooked up to HWInfo), but Valve says this version will not be sold . It serves as an example of what is technically possible, while the retail product will ship with standard plastic covers and leave any display mods to the community.
