Yes - the bezels that were supplied by OcUK needed the lower holes drilled out to fit. They were in the right place, but they were the wrong size.
I would also suggest you invest in some better fans as well, as the supplied Lian Li ones are not the best.
And they were a real pig to fit. They had to be very carefully angled through from the side. I wrapped them in kitchen towel to stop them getting scratched.
