EarthDog, I understand your point. Yes, it kinda hides the wiring from view which is fine and dandy by me too. But like yourself get a bit aggravated by remounting the grommets that pop out. Maybe gluing them in would be the best way to handle that minor irritation ? I just figure it doesn't matter all that much in the Grand Scheme of Things, not bad to have or not. I've popped one out, don't miss it, left the others in. Next case I purchase won't require them. But a bit more wiring room behind the MB tray is high on my list.
Fewer 5.25" bays, like the Antec 1100, more mounting/reconfiguration options for the 3.5" trays, and as many filters as there are fan mountings (just in case I get a hankering for reversing air flow), and sound insulation on larger panels (I guess that's a mod I should easily do myself). These are preferences on my bucket list.
