I think that if you mount fans like as following guide, it will look great. http://forums.bit-tech.net/showthread.php?s=&threadid=25455 But... your case looks cool anyway
Wow this is lookign relly good BUT... i have 2 Words for you -Short Rivets- you must have spent a butt load on those bolts and now you ahve to trim them all down and ruin the threads. That could take a couple of hours unless you have a bandsaw? The rivets would look just as good as those socket head bolts. Are you going to do a mirror finish on the metal?
Leave the nut on, hacksaw, take the nut off, making the thread good again No mirror finish, too difficult to maintain. The bolts werent expensive.
