Customization company dbrand has begun selling a Portal-themed Companion Cube case designed for Valve's upcoming Steam Machine [1].

The release allows early adopters to apply a specific aesthetic to the unreleased hardware by utilizing one of the most recognizable designs from the Portal video game series [1], [3].

Orders for the case are currently open through dbrand's online store [1], [2]. The product is priced at $100 [2]. According to the company, shipping for the cases is slated for late July 2026 [1], [4].

"We're excited to bring the iconic Companion Cube to the Steam Machine community," a dbrand spokesperson said [1].

The product functions as a cover for the gaming cube, rather than a standalone PC case. The design is intended to capitalize on the iconic nature of the Companion Cube to attract enthusiasts of the Valve franchise [1], [3].

Some industry observers have noted the unusual timing of the release, as the case is available for purchase before the Steam Machine itself has been released to the public [2], [4].

"I'm making a note here about this $100 Companion Cube cover, even though I don't know how much the Steam Machine will actually cost," a Gizmodo author said [2].

Regarding the use of the product, Anthony Karcz of Forbes said that for this experiment, the company does not recommend using the Companion Cube for anything other than display, and encasing the Valve-manufactured gaming cube [3].

“"We're excited to bring the iconic Companion Cube to the Steam Machine community."”

The launch of a third-party accessory before the official release of the primary hardware suggests a high level of anticipation and market confidence in the Steam Machine's form factor. By leveraging the Portal IP, dbrand is positioning itself to capture the enthusiast market immediately upon Valve's hardware launch.
