A tech YouTuber repurposed three fanless digital signage mini PCs from Subway sandwich shops to test their viability as gaming rigs [1].

The experiment highlights the challenges of hardware upcycling and the strict technical requirements of modern video games. While the project demonstrated a DIY approach to salvaging obsolete electronics, the results suggest that specialized industrial hardware often lacks the versatility needed for consumer entertainment.

Each of the three repurposed machines featured an Intel Core i3 processor designed for fanless signage use [2]. The creator sought to determine if these low-power units could handle popular titles despite their lack of dedicated graphics hardware or active cooling systems.

Performance tests revealed significant limitations. The machines managed approximately 15 fps while running Grand Theft Auto V [1]. "These machines can barely push GTA V past 15 fps, which is basically unplayable," the YouTuber said.

Minecraft performed slightly better, reaching approximately 25 fps [2]. However, the creator noted that the experience remained choppy. "Minecraft runs a little smoother at about 25 fps, but you’re still looking at a very choppy experience," the YouTuber said.

The attempt to turn signage hardware into a gaming platform served primarily as a technical curiosity rather than a practical guide for other gamers. The specialized nature of the Intel Core i3 signage variants means they are optimized for static image display and basic updates rather than the high-intensity calculations required for real-time 3D rendering.

Editorial staff at Tom's Hardware noted the project's value as a demonstration. "It’s a fun proof-of-concept, but the hardware simply isn’t up to modern gaming standards," the staff said [1].

This project illustrates the divide between industrial-grade embedded systems and consumer computing. Digital signage hardware is engineered for stability, low power consumption, and longevity in a fixed environment—not for the peak performance bursts required by gaming. The failure to achieve playable frame rates underscores that while basic CPU architecture may be similar, the absence of thermal management and GPU power makes such hardware unsuitable for anything beyond its original intended use.
