Rosewill overcomes the biggest problem we’ve had with medium-duty cases by adding a strap to the power supply mount. That issue, of course, manifests itself during shipping, where heavy power supplies often bend cases that aren't built using thick steel.
We should also note that the bottom filter is externally mounted for easier access. You'd have to flip the case on its side to remove it, but that’s certainly more convenient than removing a power supply. An additional 140/120 mm intake fan mount is also present, though the length of most high-capacity PSUs will typically limit you to the smaller size.
