Im upgrading an R930 from the four hdd sff to 24 hdd sff. The front bezel is not compatible and has to be changed. Problem is how does it come off? Are the rack ears holding the bezel on somehow?

I tried to take the ears off but theyre on there with either security screws or some screw head type Ive never seen before.

The kit is on the way from China, I hope, but I'd like to get a jump start on it now that I have time. Any help is greatly appreciated.
