Hi whitewiz,
I think some additional comments are appropriate - independent on the final value for your filter pole (10 MHz or 100 MHz):
A factor of 10 between opamp transit frequency and filter cut-off (as proposed in the last reply) may be sufficient in order to meet the required corner frequency roughly. However, don´t forget you are going to design a HIGHPASS which must not attenuate frequencies ABOVE the corner frequency (until which maximum ??). I doubt if the mentioned factor of 10 can do this with a sufficient accuracy for frequencies higher than two times the corner frequency.
As far as the mentioned Sallen-Key-topology is concerned - I recommend to use no other gain values than 1 or 2, because these values are easy to design.
Added after 5 minutes: During selection of an opamp don´t forget to look for a suitable slew rate.
