100mm 26" forks are around 470-475mm a-c. Take away a generous 30% sag, and you've got rigids sitting around 440mm. 420-425mm rigids are meant to replace 80mm sus forks, but can give some nice sharp handling, assuming the BB doesn't get too low :-)
Those Psylos sound particularly long, compared to the assortment of Rockshox, Marzocchi, Fox & Magura forks I've owned.

Between 420-440mm a-c will work for 100mm 26" frames, depending on how you prefer the bike to handle.
