Well, Computex Taipei still hasn't formally kicked off, but it looks like it's close enough for VIA and Shuttle, who have now gotten official with that Nano-based small form factor PC that first surfaced earlier this week. Now dubbed the Shuttle XS29F, this particular version comes equipped with the low-power combo of VIA's Nano U1700 CPU and VX800 media system processor, along with support for up to 4GB of RAM, your choice of SATA II storage options, both VGA and DVI ports, four USB 2.0 ports and, perhaps most importantly, a maximum power consumption of just 50 watts for the entire system. That, as VIA helpfully explains in the video after the break, means the system can ditch all the usual fans and heatsinks and remain nearly silent during operation, not to mention let you save you a bit on your energy bills. Still no word on a price, sadly, but we're hoping Shuttle will be a bit more talkative once Computex opens its doors.
