The idea is to build something resembling the GPD MicroPC for roughly the same cost but with a better processor. To that end an i3-7100U on a mini pc motherboard (125x125mm) will be used as the starting point. A 1920x1200 7inch display will be used (I think these are used in VR headsets). Folding keyboard and a large battery will also be part of the design. The target OS will be Linux (probably Debian with Unity desktop environment) though Windows will also be possible because the i3 is an x86_64 processor.
