It's a good case, there's one sitting on my desk. The V5 wouldn't mount with my SF600 the way I wanted (holes didn't line up IIRC) but I was able to use silverstone's SF to ATX PSU adapter plate. Let me fit a monster Noctua C14S in mine, but it's tight.
I'm considering going with a ghost, dancase or SM500 for the next round or picking up a V6. My only complaint is the system on air can be a little loud, but it's got a lot stuffed in there and I could always look at a small WC system the next build.
