Spotted by Fanlesstech.com, Asus' newest VivoMini PC will be available in three versions, with quad-core Pentium N3700, quad-core Celeron N3150 or dual-core Celeron N3000. The precise dimensions are set at 131x131x42mm (0.6-liter chassis) and it packs quite a few features for its size.
The full list of specifications include 2GB of DDR3L 1600 RAM, expandable up to 8GB in two SO-DIMM slots, up to 128GB of M.2 10Gb/s SSD storage, three USB 3.0 ports, gigabit Ethernet, integrated 802.11ac WiFi and Bluetooth 4.0, couple of USB 3.0 ports, HDMI and D-Sub or mini DisplayPort outputs and standard audio jacks. It ships with Windows 7 Pro or Windows 10 Pro OS.
It is important to note that only the Celeron N3000 based SKU will be completely fanless while the Celeron N3150 and Pentium N3700 will have some sort of active cooling. It will ship with 45W or 65W power brick, depending on the SKU.
Unfortunately, none of those Asus VivoMini SKUs are listed in Europe or the US so we do not have any info regarding the price. In any case, Asus VivoMini UN45 SKU with passively cooled Celeron N3000 certainly sounds interesting.
