Valve picked an awkward moment to remind everyone that its $1,049 Steam Machine is optional. On the very week the living-room console finally goes on sale, the company quietly confirmed that you don’t actually have to buy one. Plug a spare gaming PC into the television, install the latest version of SteamOS, and you have built the same thing yourself — for whatever the parts in your closet are worth.
The admission came from Pierre-Loup Griffais, a longtime Valve engineer, in an interview that The Verge ran and the gaming press picked up on 22 June 2026. His phrasing was almost offhand. Starting with the SteamOS 3.8 release, you can put together your own Steam Machine using whatever PC parts you want.
For a company that has spent months building anticipation around a sleek little cube, it was a strikingly casual way to undercut the pitch.
What changed is the operating system, not the hardware. SteamOS began life as the software baked into the Steam Deck handheld, tuned for one specific chip. With the 3.8 update — the 3.8.10 build is the one now rolling out — Valve has been widening that compatibility to ordinary desktop components, including recent Intel and AMD platforms. The result is that the controller-first, couch-friendly interface Valve sells as the Steam Machine’s main draw is no longer locked to Valve’s own box.
The price gap is the whole story. The official Steam Machine, Valve’s compact unit built around a custom AMD Zen 4 processor and a semi-custom RDNA 3 graphics chip, starts at $1,049 and climbs past $1,400 once you add storage and a controller. It targets 1440p and 4K gaming with upgradeable DDR5 memory and NVMe storage up to 2TB. Those are respectable numbers, but they are also numbers a lot of existing PCs already match or beat — which is precisely the tension Griffais walked into. Anyone who read the early benchmarks for Valve’s “Fremont” hardware could already see the machine landing in the same neighborhood as a midrange desktop rather than miles ahead of it.
So why ship a console at all? Because most people don’t want to think about parts, drivers, or BIOS settings, and the appliance does that thinking for them. The DIY path is aimed at the slice of buyers who already own capable hardware and would rather repurpose it than spend four figures again. Griffais was clear-eyed about who that is. If you have something that is similar to the use case of a Steam Machine, where you have a PC that’s gonna be plugged into a TV, and has a single hard drive that you’re not going to try and dual boot […] you can put SteamOS on there.
That sentence carries a quiet warning. The smoothest experience right now assumes you are willing to wipe a drive and dedicate it entirely to SteamOS. The system still doesn’t offer a clean way to dual-boot alongside Windows, the arrangement most enthusiasts actually run. Griffais framed it as unfinished business, describing a hoped-for future where SteamOS can coexist with a different operating system
on a desktop — but that future isn’t here yet. For now, build-your-own means commit-your-own.
The other asterisk is Nvidia. SteamOS leans on AMD’s open-source graphics drivers, which is why Intel and AMD machines are the easy targets. Nvidia cards — by far the most common in gaming PCs — are a harder problem. Valve says it has a growing team on it. We’re collaborating with Nvidia very closely,
Griffais said, while cautioning that support may not arrive this year. Until it does, a large chunk of the PC-owning audience can read the announcement but not act on it.
None of this reads like a company hedging. It reads like Valve doing what it has always done with Steam: treat the storefront and the software as the product, and the boxes as one delivery method among several. Selling hardware was never the point so much as keeping players inside its ecosystem and away from a Windows desktop where Microsoft, not Valve, sets the rules. The same instinct sits behind the broader SteamOS desktop push, and behind Valve’s recent hardware buildup; the cube is simply the most visible piece of it.
The honest read is that Valve has given itself two ways to win. If you want the tidy appliance, it will sell you one. If you already have the muscle and resent paying twice, it will hand you the software for free and let your own tower do the job — provided you’re running the right silicon and willing to give up a drive. Either way, the machine Valve most wants you using isn’t the one on the shelf. It’s SteamOS.
