Is there a new Enlight 7237 case?

[Technics1200]

Not the p4 case, but I'm talking about a newer one. I bought one last night and the rails don't like click in, they have to be screwed in. I'm wondering if this is the older version of the case. I rather have the click in rails. Also this is the three piece case meaning I can take off the face, and both side plates. Is this new, or old?
