Does RB532A fit the CA800 / CA600 case?

I know there is CA532, but it seems to be at least 2times expensive than CA800 or CA600. So the question is:

If i drill missing holes for leds, can I put RB532A into CA800 or CA600 case?

For me it seems it should be possible as front port layout and mounting holes looks to be the same. Can anyone confirm this?
