Mick are you taking selective input only? I had posted some feedback for your case above ^^ but if you're not interested then I won't be bothered I guess. After further inspection it looks like your case will allow a rad mount on either side, is this true? If so that would negate the counterbalance need as users could place the rads wherever they like based on their own tests. Also, although minor, the plastic/rubber cutouts on the corsair obsidian are a really great addition IMHO. It also seems like an easy thing to add, while allowing more complex wire management situations.

Looking forward to your reply!
