This is a funky plastic enclosure for the A20-OLinuXino-Micro and A20-OLinuXino-Micro-4GB boards. It consist of two plexiglass plates, eight M3 screws and twelve metal spacers which assemble together. There are four additional holes where you can attach 2.5″ SATA HDD (as shown in the pictures). The dimensions follow the A20-OLinuXino-Micro PCB's dimensions - (5600 x 3250) mils.
Please Note: the SATA hard drive is not included.
