Intel tasked its engineers with building the absolute smallest fully featured compute unit possible. The result is something Intel markets as the Next Unit of Computing. This isn't a standard form factor (yet), but it's fully featured. The 4" x 4" motherboard features an integrated Core i3 with 7-series chipset, mini-PCIe slot, mSATA slot, two SO-DIMM slots and three USB ports. Power is supplied by an external AC/DC adapter, but there's also a small 2-pin header for an optional internal power supply. There's also an ethernet jack and two HDMI outputs.

Since the NUC isn't yet a standard form factor, Intel had to work with a chassis vendor in putting together a reference platform. The result is this:

Later this year you'll be able to buy this chassis, power supply and Core i3 equipped motherboard for around $399. That price won't include an OS but it will include a smallish mSATA SSD.
