The PC-B71 is different via the lower part of the front bezel which has an integrated HDD Hot swappable SATA cage with a front facing securely lockable door.
They do have points 2 and 3 covered pretty much (you can get 15mm spacing triple fan roof panels for the A70/71, which should fit the newer cases based on the same chassis)..... and if they covered point 2 what would Tommy boy do.
I'll admit it IS a little boring seeing the same internals again and again, but lets face it, what other cases can so easily accommodate such a large amount of radiator area?
