To install the fanless HP640 I chose a vertical position with spacers for best heat transfer. On this thin client I run a home assistant server very powerconsumption-effective.

The spacers are split from the baseplate for better printability.

Printed in Prusament PETG (matte black); 0,4mm hf nozzle; 0,20mm structural; brim

print time 2h 14 min; 44g

I used 4 x M4x16 DIN 7380-1 oval head screws (?) (Linsenkopfschrauben; See attached pic. L=16mm) to connect the baseplate, spacers into the vesa 100 mount of the device.
