This is possibly the smallest PC Testbench with dual 360mm Radiator Support.
It has mounting for ATX motherboards and therefore also ITX. mATX can be mounted as well but is not supported on the bottom two screw holes. eATX should also work but will also have unsupported screw holes if additional ones are used.
i recommend to print the parts with high infill and extra walls compared to normal print settings. to increase rigidity you may want to use glue.
The Motherboard and Expansion Card mounts have holes for M3 heatset inserts.
two 2.5" SSDs can be mounted on the back support. watercooling pumps can be secured to the bottom of the back support with zipties/velcro straps.
some radiator screws may be too short to reach through the 3d printed mounts. spacers are provided for using longer screws without damaging the radiator.
