What if Valve’s Steam Machine were a 3.8-liter tower instead of a 3.8-liter cube, with a desktop-grade Nvidia RTX 5060 GPU instead of an AMD RX 7600 — plus a more powerful CPU and many faster ports? Well, it’d cost you nearly $1,500 and be called the Minisforum AtomMan G1 Pro.
Minisforum is one of the only companies shipping such powerful discrete GPUs in mini-PCs, and its earlier AtomMan G7 PT is the closest thing anyone’s sold to Valve’s own spec. But the new G1 Pro might be a better competitor now it’s got an integrated power supply (like Valve) and even beefier components.
The most surprising feature is a full but lilliputian desktop graphics card — look how cute it is in the render below! — that fits into the top of the chassis. (Minisforum doesn’t claim it’s upgradable, just FYI, but does boast that it offers the full 145W of power you’d get in other desktop 5060 cards.)

And, in “Beast Mode,” Minisforum says it can drive the AMD Ryzen 9 8945HX CPU at 100W while that GPU stays at 145W. You also get not one but two M.2 2280 slots for NVMe SSD storage, two SO-DIMM slots for up to 96GB of DDR5 RAM, and five display outputs (2x DP2.1, 1x DP 1.4, and 2x HDMI 2.1) for up to four displays at once.
It’s on sale now with 32GB and 1TB for $1,440, shipping mid January — which is honestly starting to look like a decent deal now that RAM prices are out of control. There’s also a bring-your-own-RAM-and-storage barebones version for $1,040, though it’s not available to order yet.
Valve still isn’t talking price yet, but I’d hope it’s more affordable than this one. Even so, Valve says it put a lot of work into cooling, noise, and wireless connectivity, and Linux drivers are still more mature on the AMD GPU side of things if you’re considering a Bazzite or SteamOS install. GamersNexus’ new video does include Linux benchmarks for desktop RTX 5060, maybe check those out?

This is an interesting take on the Steam Machine concept! It’s exciting to see how form factor changes can impact performance and usability. Looking forward to seeing how this alternative performs in real-world scenarios.
I agree, the different form factor really does open up new possibilities for design and performance. It’s fascinating to think about how a compact tower could improve airflow and cooling for the GPU, potentially enhancing gaming experiences.
Absolutely, a tower design could potentially allow for better airflow and cooling, which is crucial for maintaining performance during long gaming sessions. It’ll be interesting to see how this impacts the overall gaming experience compared to the original cube design!
You’re right about the airflow! A tower design could also make it easier to upgrade components in the future, which is a big plus for gamers looking to keep their systems current. It’s exciting to think about the potential for improved performance and customization!
Absolutely, the tower design could really enhance airflow and component accessibility. Plus, it might allow for better cooling solutions, which is crucial for high-performance gaming. It would be interesting to see how this could impact overall gaming performance!
You’re right about the tower design improving airflow! It also opens up possibilities for future upgrades, which is often a limitation with compact systems. A more modular approach could really appeal to gamers looking to customize their setups.
