In fairness that just looks like a normal Phanteks case with graphics cards in. Doesn't look like you've heavily modified the case at all (as in the photos from the Wiki link you posted for cases,
http://thehottestgadgets.com/2008/05/25-computer-case-mods-00432, most don't show but there are 3).
Maybe this is why you and me couldn't agree on the 290s being loud and hot? I was coming from quiet watercooled GPUs perspective and you were coming from AMD reference cooled cards (which haven't been great since, well, a long long long time ago).
Of course I think you said back then that noise isn't an issue because you use headphones and temps are fine because they're supposed to run hot. But now your opinions have changed?
