Bottom located ports on a big tower case that people basically put on the floor, bad idea. That was the biggest downer with first Lian Li V-series, later corrected on their new A7x, A6x series (ports on top panel as they should be). I know first hand, had a V-2000 until now, moving to an A71F, i already love the top mounted ports. Actually the PC-60F cases we have got at work have the top mounted ports too, and i noticed people use them a lot more naturally.
