Could you get around the grounding issue by installing rubber grommets beneath all screws? Do other cases like the Lian Li or Sentey cases have grounding issues?
I wouldn't have any idea. Anybody that has had that issue certainly didn't rebuild with the same case to see if rubber grommets would do the trick haha.
For whatever case you do buy, make sure it is tool-less. The convenience of having a tool-less case is something you wont understand until you've actually had one.
