MSI introduces its ProBox series of compact barebones, starting with the ProBox23.
The machines are meant to be very compact, and as such this specific model measures just 202 x 204 x 55 mm. This compact size is accomplished through the use of a thin-type Mini-ITX board, which is based on an Intel H81 chipset and draws its power from an external power brick. This motherboard can take CPUs that drop into the LGA1150 socket and carry TDPs of up to 65 W. Regarding memory, you'll be able to have up to 16 GB of DDR3 SO-DIMM memory.
Also present in the machine is support for two 2.5" drives, a single mSATA drive, as well as a single half-height Mini-PCIe slot. There is no further room for expansion cards.
Front I/O is handled by a quadruplet of USB 2.0 ports as well as the standard set of HD audio jacks. Rear I/O is dealt with by a power plug, a single eSATA port, an HDMI port, two USB 2.0 ports, two USB 3.0 ports, a single Gigabit Ethernet port, as well as stereo line-out and microphone-in jacks.
The unit can also be mounted to the back of monitors, as it has support for VESA mounts.
Pricing remains TBA.
