From the Shuttle Website:
“Powerful 2nd Generation
With class-leading power, the Shuttle® X6100 delivers the performance of bigger, tower-sized desktops in an ultra compact design. It’s less than 3-inches tall, and yet packs in powerful 2nd generation Intel® Core™ processors – Core™ i3, Core™ i5, and Core™ i7 – the latest Intel® H61 chipset, and up to 16GB of memory.
Capable, Yet Flexible
Shuttle® X6100 brings more capability and performance to the ultra small form factor desktop, including HD video, impressive graphics, responsiveness, scalability, and dual-monitor support.
With this level of power and flexibility in a small package, X6100 is ideal for the home, office, and even in specialty markets such as digital signage and point-of-sale.
Low Energy Consumption“
