Or you could go the other way and count it down to a pulse-per-minute, then drive a clock intended for a pulsynetic or similar master clock system. They will mostly be large analog clocks but digital clocks also exist. Still intended for display rather than a panel, but a 19" rack panel would fit.
I'm dividing down 10MHz to 50Hz using one of TvB's dividers, then generating a 50Hz square wave at 6V. This powers a small LED clock intended to be run from mains power via a transformer.
