This ought to fan the rumour flames a bit; it appears Valve is hiring hardware development specialists for a new hardware project.
A rather intriguing job listing on Valve's site for an 'Industrial Designer' shines light on the firm's disappointment with today's PC hardware, and suggests it will soon be taking matters into its own hands.
"Valve is traditionally a software company," reads the post. "Open platforms like the PC and Mac are important to us, as they enable us and our partners to have a robust and direct relationship with customers."
It gets more interesting from there. "We're frustrated by the lack of innovation in the computer hardware space though, so we're jumping in," Valve declares. "Even basic input, the keyboard and mouse, haven't really changed in any meaningful way over the years. There's a real void in the marketplace, and opportunities to create compelling user experiences are being overlooked."
The candidate is required to have "6+ years of professional experience shipping world-class, high-tech hardware products", and "confidence with 2D and 3D design visualization tools".
Valve has previously dismissed rumours that the firm is working on releasing its own hardware dubbed the 'Steam Box' - a console-like machine that would play Steam games and other PC titles on your telly with a proprietary controller and optional USB attachments.
But the rumored claims don't seem so far-fetched now, do they?
