Habey has introduced two iterations of a new low-powered ultra-compact computer, the BIS-6620-I and BIS-6620-II. As the models indicate, both are very similar. The first features a 1.1GHz Intel Atom Z510 processor, VGA and S-Video ports, and four USB 2.0 ports (divided evenly between the front and back), while the second has a 1.6GHz Atom Z530 processor, DVI-out, and only two USB 2.0 ports (front).
Both systems feature a fanless design and have a single SODIMM slot with support for up to 2GB of RAM, full hardware acceleration for H.264, MPEG2, MPEG4, VC1, and WMV at up to 1080p, a CompactFlash slot, an SD reader, a 1.8-inch internal SATA II drive bay, one PS/2 port, gigabit Ethernet, optional wireless, and mic and headphone jacks. They run your choice of Windows or Linux.
Measuring only 120 x 120 x 40 millimeters and weighing just over a pound, it wouldn't be difficult to find a home for the BIS-6620 nettops, but they're mountable if you're out of desk space. Pricing starts at $300.
