Lian Li B4 Flat-mount SFX PSU Cage

This is the SFX version of the power supply cage. There is a flat-back version and one with integrated spacing at the back. The spacing is optional but reduces cable management room behind the PSU.

The flatback version is easier to print (print back flat on the bed), and you can optionally print two of the top spacers and one lower spacers for the offset.

For the integrated version you will have to determine which orientation works best for your printer. I recommend appropriate supports for both versions. The integrated spacer version will be slightly stronger as it will engage more of the screw threads. The SFX version is positioned so that a 25mm top fan can still clear. Good cable management is recommended. It is recommended to tap 6-32 threads at the screw holes.

Note: While the cage can fit SFX-L, it will sit too low and prevent a longer GPU from seating.
