The Steam Machine offers a unique, console-like experience that hides a capable gaming PC underneath. While official accessories are currently limited, you can still personalize your hardware and push its performance with a few strategic upgrades.
1. Customizing Your Steam Machine Faceplate
Because the Steam Machine features a magnetic faceplate, swapping your look is simple. Currently, most third-party skins are scarce, and high-profile options like Dbrand’s Companion Cube enclosure were canceled. If you want to improve your machine's thermals, the GamersNexus SteamVent Downpour is your best bet; it replaces the stock panel to increase airflow for your CPU and GPU. Just be aware that it can lead to higher SSD temperatures due to redirected airflow.
If you prefer a DIY approach, Valve has open-sourced the CAD files and firmware for their E-ink 'Inkterface' display, allowing you to build your own. Accessory maker Jsaux is also planning to release clear enclosures and E-ink displays later this year.
2. Expanding Internal Storage
Upgrading the Steam Machine's storage is the most practical modification you can make. While you can pay Valve for a 2TB upgrade, you can install up to 4TB yourself. The WD Black SN7100 4TB M.2 NVMe SSD is the current recommended pick, offering 7,000MB/s sequential read and 6,700MB/s write speeds. At roughly $590, it provides a solid balance of performance for the price.
3. Picking the Right Cables
The Steam Machine comes with an HDMI cable capable of 4K at 120Hz, but if you need extra length or want to prepare for future HDMI 2.1 support, the Cable Matters 10ft Ultra High Speed HDMI Cable (3-Pack) is a reliable choice. These cables are fully compatible with current HDMI 2.0 specs while offering a path for the higher bandwidth of HDMI 2.1.
4. Steam Controller and Alternatives
If you are looking to customize your Steam Controller, Dbrand currently offers a variety of skins, including glow-in-the-dark circuit board designs and various solid colors. If you prefer a different gamepad, the Sony DualSense is an excellent alternative due to its similar stick layout and built-in touchpad. Other reliable options include the 8BitDo Ultimate 2 Wireless Controller and the GuliKit KK3 Max.
5. MicroSD Storage
For additional, non-internal storage, the SanDisk Extreme 1TB MicroSD Card is the most cost-effective choice. Note that the Steam Machine only supports UHS-I speeds, capping out at 104MB/s. Do not pay extra for newer, faster cards, as the hardware cannot take advantage of the higher speeds.
How to Choose Your Own Accessories
Since the Steam Machine is essentially a small gaming PC, your options for accessories are vast. When shopping, always verify if the device has Linux/SteamOS support. Be cautious of sponsored content on YouTube and Amazon reviews; if a creator praises everything they review regardless of quality, their recommendations are likely not reliable. When in doubt, consult enthusiast subreddits for real-world user experiences.
