Shuttle will present an even smaller form factor at CeBIT next month, Register Hardware reports.
Not much details are known but this new form factor will be smaller and even more quiet, making them even better to put in living rooms.
"We introduced the world's first small form-factor PC five years ago," Shuttle head of marketing in Europe Melanie Liu said. "The time to set another milestone has arrived."
Shuttle's current XPC line up isn't exactly tiny - they're much larger than Apple's Mac Mini and AOpen's Mac Mini-like "Mini PC", for example - so there's room, as it were, for Shuttle to compact its cases even further.
