This Is A Triumph—Dbrand Converts Steam Machine Into Companion Cube

Dbrand has turned the Valve Steam Machine into a literal Companion Cube — but don’t expect to play games on it. The mod is for display only.

The skin-and-accessories company Dbrand announced a conversion kit that transforms Valve’s Steam Machine gaming PC into a weighted Companion Cube, the iconic object from the Portal video game series. The announcement was made on June 22, 2026, via Forbes. The kit is officially licensed by Valve and is designed to encase the entire gaming cube in a hexagonal, paneled exterior reminiscent of the Companion Cube from Portal. Dbrand warns that the mod is strictly for aesthetic display and not intended for active gaming use.

Dbrand previously has a history of creating playful, high-quality skins and cases for gaming hardware, including custom wraps for Steam Deck, PlayStation 5, and Xbox consoles. This collaboration marks a deeper partnership with Valve, leveraging the Portal franchise’s nostalgic appeal to attract both collectors and gamers. The Steam Machine itself was first introduced by Valve in 2015 as a small-form-factor gaming PC, but it never achieved mainstream success. This conversion kit breathes new life into the device as a collectible.

Specific details about the product remain scarce, but the limited-edition Companion Cube conversion kit is expected to be produced in only 500 units, according to industry speculation. Pricing has not been officially confirmed, but comparable Dbrand custom skins often range from $50–$100. The kit includes precision-cut panels that fit over the existing Steam Machine chassis, transforming it into a perfect replica of the Companion Cube with the signature pink and gray color scheme. Dbrand explicitly states that the kit is intended for display and encasing, not for active gaming, likely due to heat dissipation concerns.

Gaming culture observers note the move taps into the enduring popularity of Portal, which recently celebrated its 15th anniversary. The Companion Cube has become a symbol of loyalty and sacrifice in the gaming world. By turning a real piece of gaming hardware into that cube, Dbrand is creating a conversation piece that bridges digital nostalgia with physical design. Industry analysts point out that such collaborations help extend the lifespan of niche hardware while generating buzz for both brands.

The conversion kits are expected to go on sale later this year through Dbrand’s website. Fans should act quickly if they want one, given the limited run. This product may also signal future collaborations between Dbrand and Valve for other Portal-themed accessories. For now, the Steam Machine Companion Cube stands as a triumph of gaming memorabilia, even if it’s not meant for actual gaming.
