While official Steam Machine accessories are currently hard to find, you can still elevate your experience by focusing on the device’s desktop-PC architecture. From thermal-improving faceplates to essential internal storage upgrades, there are plenty of ways to customize your machine right now.
Key recommendations include the GamersNexus SteamVent Downpour for thermals, the WD Black SN7100 4TB SSD for massive storage, and reliable controller options like the Sony DualSense. Since the Steam Machine operates as a standard gaming PC, most PC-compatible hardware—including microSD cards—will work seamlessly.
