Yep the case plastics are hanging over the edge of the Chassis in between the vertical members on that side. That's why it needed to be mounted back there for the pics.

Upside down? No can do, I need the pretty, moving parts pointing up or it's not up to spec for one of my hacks . . .

. . . besides, I have to remove the plastic front bezel of the chassis to get it close enough to the slot anyway. [] ]'>

On the gripping hand, when it comes to fitting MoBos, I'll whack those puppies into a compact upside in a heartbeat any day! :lol:
