That Steam machine prototype wasn't the only Zbox in Zotac's bag of CES goodies. Earlier this morning, the company also announced the Zbox nano ID67, an even tinier machine that's powered by a 15W Haswell processor.
The Zbox nano ID67 features the Core i3-4010U, a 1.7GHz Haswell chip with dual cores, quad threads, and Intel HD Graphics 4400. There's no discrete GPU accompanying that processor, so while the system should be able to handle casual games and older titles, it probably won't run Battlefield 4 with the detail cranked up. That's excusable, given how tiny this thing is.
CPU aside, the Zbox nano ID67 has room for one DDR3 SO-DIMM and one 2.5" hard drive. There's a card reader up front, and connectivity is quite plentiful. Included are two USB 2.0 ports, four USB 3.0 ports, DisplayPort and HDMI display outputs, Gigabit Ethernet, 802.11ac Wi-Fi, and Bluetooth 4.0. (I even see a rear eSATA port in Zotac's photos, although that's not mentioned in the specs, strangely enough.)
For folks who'd rather not get their hands dirty, Zotac will offer the Zbox nano ID67 Plus, a version of the ID67 pre-configured with 4GB of DDR3 memory and a 500GB mechanical hard drive. Like the ID67, the Plus will ship with a VESA mounting bracket, so you can strap it behind your monitor to save desktop space.
