I see that the items I called caps below are actually inductors with plastic covers over them, on the newer picoPSUs; but that’s a nit.

My picoPSU fit without requiring any grinding, but I notice that some of the later picoPSUs have two larger caps on the side now that make them a bit wider than the earlier versions so perhaps that’s what you have.  I did grind a portion of a few of the internal rails near P1 and P2 to make it easier to plug and unplug blaster cables.

The outside of the PicoPSU is just a couple of millimeters too wide.  I had to grind some slot rails off the inside end of the Hammond enclosure.
