AMD engineer builds a 3D-printed Steam Machine rival with an RTX 5060

This custom-built Steam Machine squeezes an RTX 5060 GPU into a tiny case

Following Valve's announcement of the  $1,049 / 1,039€ / £879 Steam Machine featuring semi-custom RDNA 3 graphics, many wondered if a superior system could be built within the same compact dimensions. AMD engineer Jacob Terkelsen investigated this possibility, confirming that it is indeed achievable.

A creator on Printables, known as 3DCatt, has designed a 3D-printable Steam Machine-inspired PC case that supports Mini-ITX motherboards and low-profile graphics cards, allowing enthusiasts to assemble their own compact gaming PC.

AMD engineer Jacob Terkelsen has already showcased one such build. Interestingly, despite working for AMD, his system uses a low-profile Gigabyte GeForce RTX 5060, rather than a Radeon GPU. The choice makes sense, as there are currently no low-profile Radeon RX 9000 series graphics cards available. However, it does come with one downside: because SteamOS doesn't officially support Nvidia GPUs, the system can't take full advantage of Valve's Linux-based operating system.

The build demonstrates that matching the Steam Machine's compact footprint with off-the-shelf components is entirely possible, although it requires some fairly niche hardware. Alongside the RTX 5060, Terkelsen's system includes an AMD Ryzen 5 5500, 16GB of DDR4-3200 memory, and a 512GB NVMe SSD.

Performance should comfortably exceed Valve's own hardware. The Steam Machine features a semi-custom RDNA 3 GPU believed to offer performance roughly comparable to a Radeon RX 7600M, while the desktop RTX 5060 provides a noticeable step up in graphics horsepower.

Building inside the custom enclosure isn't without compromises, however. The design requires several uncommon components, including a Flex ATX power supply and a low-profile PCIe graphics card, both of which are far less common than standard desktop hardware. The showcased build also relies on a 400W Flex ATX PSU, limiting the overall power budget available for higher-end CPUs and GPUs.

Cooling could also become a limiting factor. Given the case's compact dimensions and relatively limited ventilation, fitting more power-hungry hardware may lead to higher temperatures and increased fan noise.

Even so, the project highlights the flexibility of the PC ecosystem. For enthusiasts who like Valve's compact console-inspired design but prefer choosing their own hardware, this 3D-printable case offers an intriguing alternative. As interest in the Steam Machine grows, it's likely that more custom cases and small-form-factor builds inspired by Valve's latest hardware will begin appearing in the months ahead.

Très intéressant de voir qu’on peut construire une machine bien plus performante que la Steam Machine officielle Valve, avec une RTX 5060 à profil bas et un Ryzen 5 5500.
It's very interesting to see that you can build a machine that's much more powerful than the official Valve Steam Machine, with a low-profile RTX 5060 and a Ryzen 5 5500.

Me gusta mucho más esta filosofía que la de cerrar el hardware. Aquí se ve que el formato compacto puede ser flexible sin sacrificar demasiado rendimiento.
I much prefer this philosophy to the one of closing off the hardware. It shows that a compact form factor can be flexible without sacrificing too much performance.

C'est une belle démonstration technique, mais je me demande combien coûterait réellement une configuration comme celle-ci. À budget équivalent, une tour classique offrira probablement de meilleures possibilités d'évolution
It's a nice technical demonstration, but I wonder how much a setup like this would actually cost. For the same budget, a standard tower PC would likely offer better upgrade potential.

Super concept ! Ça montre qu'on peut se monter un PC ultra compact, plus puissant que la Steam Machine, avec des composants du commerce. Certes, il faut quelques pièces un peu spécifiques, mais le résultat est vraiment sympa pour ceux qui aiment bricoler et personnaliser leur config. Une excellente alternative pour les fans de petits formats !
Great concept! It shows you can build an ultra-compact PC, more powerful than the Steam Machine, using off-the-shelf components. Sure, you need a few specific parts, but the result is really cool for those who like to tinker and customize their setup. An excellent alternative for fans of small form factors!

Siempre me atraen estos montajes mini-ITX porque parecen pequeños milagros de ingeniería. Aun así, luego recuerdo que el cableado, el flujo de aire y la fuente mandan mucho.
I'm always drawn to these mini-ITX builds because they seem like little engineering marvels. Even so, I then remember that cabling, airflow, and the power supply are crucial.

Cool project but not really a realistic alternative for most people. You need a 3D printer, know how to build in that form factor, and deal with a 400W PSU that barely works. Steam Machine at $1049 is overpriced but at least you dont have to build it yourself.

3D printing the steam machine is 1 thing but i totally forgot Valve said their steam machine is moddable if we wanted to. technically you could make it better yourself instead of saying "1000$ isnt worth"... i guess its a pc after all, not like the switch 2 where if u tried u get your console bricked xD

Le concept est vraiment intéressant et j'aime beaucoup l'idée d'avoir une machine aussi compacte avec une telle puissance. En revanche, je me demande si, sur une utilisation prolongée, la ventilation ne risque pas de posé problème
The concept is really interesting, and I love the idea of having such a compact machine with so much power. However, I wonder if the ventilation might be a problem during prolonged use.

La idea es buenísima, pero depender de una impresora 3D y componentes muy específicos hace que esto no sea precisamente un PC para todo el mundo.
The idea is great, but relying on a 3D printer and very specific components means this isn't exactly a PC for everyone.
