 yes.  no metal except that of the LCD (which i recall was 400g).  no
SSD, no HDD, no fans, no heatsinks (except the metal of the keyboard
is in direct contact with the metal of the CPU Card case).  it's a
good illustration of the "mass decompounding" effect, a phrase first
used in the vehicle industry.

 you can check for yourself by downloading the GPLv3-licensed 3D CAD
source code.

 the LCD is listed on the rhombus-tech page, from which the datasheet
may be sourced, and there is approximately 2mm left and right, about
10mm top, about.... 25mm at the bottom.

 that gives the overall dimensions.
