The Mini-ITX board below is from MSI and will be out by the end of the month. When it does become available, it will be priced under $60.
The J18001 boasts Intel’s 2.4 GHz dual-core Celeron J1800 (hence the name of the board), as well as support for up to 8 GB of RAM via two DDR3-1333 SO-DIMM slots, and two SATA Gbps ports, one PCIe slot, Gigabit Ethernet, 7.1 channel audio, USB 3.0 (x1), D-Sub, DVI, and HDMI. If you’re not feeling the dual-core version, MSI says there will be a version with the more powerful quad-core Bay Trail-D out in January/February for only ten bucks more.
The quad-core Bay Trail-D comes with 2 MB of L3 cache as opposed to the 1 MB in the dual-core model and comes in two flavors, the Pentium J2900 and the Pentium J2850. The former packs a graphics clock rate of 896 MHz, while the latter boasts a graphics clock rate of 792 MHz. The Celeron J1800 features the same 792 MHz graphics clock rate as the Pentium J2850.
