I'm building a new computer with a friend at the moment, but we've installed the front fan and discovered that it blocks access to all of the 3.5" bays. Any devices we put there stick way out for the screw holes to line up (we had to mount the SSD backwards for its holes to line up).
The fan is on the inside of the case with the screws on the outside going in (that's the only way the case works for it to be installed).
Did we do something wrong? Does this case just have a really crappy design? This is the case in question.
