When you say to short are you saying that it doe not reach the second screws in the back of the hard drive cage?
UPDATE:
I see what you are saying now. You are going to have to purchase a full size adapter. The one I linked is full sized. The one you have is designed to fit into the hard drive trays that newer cases come with. I hope that helps!
I updated my post with some information for you. I will re-post it here.

there are mounting rails that came with the case, you are supposed to screw the adapter to the rails and then slide it into the cage, i know, i have that case myself!
