How do I remove these metal things

[ErNciLator]

So... going to try and explaint this.

Iv got one of these convertors that sits in 3 5.25 bays and converts them into 5 HD bays.

BUT my 5.25in bays have like shelfs for the CD ROMS and these kinda get in the way of the new-doc thing. They're like metal things that stick out on each side beneath the CD ROM (?).

Is there anyway to remove these? They look like they are cut out and folded in - how hard is it to reshape this metal stuff or chop them off?

mmm some cheap kinda case, ill get the name earlier - nothing fancy. But im pretty sure it's like steal? Or somthing hard to bend with hand at least, not going to happy.

What ways are they to mutilate? Im pretty sure this will be the only one.
