Is it a bird? Is it a plane? No, it’s the Steam Boy, a Steam Deck crammed inside a Game Boy-like chassis
The Steam Boy is a fan-made custom modification of the Steam Deck that reimagines the popular gaming device within a Game Boy-inspired form factor. Created by Reddit user PhyFawkes, the project leverages the Steam Deck’s relatively compact motherboard to house the hardware within a custom 3D-printed PETG shell that mimics the iconic Game Boy chassis design—while remaining “legally distinct.”
The motivation behind the project stems from addressing a key limitation of the standard Steam Deck: its size. Despite being considered an excellent handheld gaming PC, many users find its form factor unwieldy for portable gaming. PhyFawkes’ solution demonstrates whether the core Steam Deck components could be successfully relocated into a significantly smaller, more portable chassis without compromising functionality.
The custom hardware achieves this through careful engineering of the 3D-printed case, which maintains compatibility with the Steam Deck’s internal components. This community-driven modification showcases the flexibility of the Steam Deck’s modular design and the ingenuity within the handheld gaming community to push hardware boundaries.
The project gained attention through tech media coverage, including documentation by Tom’s Hardware, highlighting ongoing interest in custom hardware modifications and form factor experimentation within gaming communities.
