The Phantom is a great case but ultimately the decision comes down to personal taste and preference for whatever your needs are.
DF-85 is ugly. Skip to 0:25 for lulz
It has the very awesome "Fleet Release doors" and nice 2.5" Drive hot-swap bay.
Those Series have some fail points, the optical drive lulz like mentioned in the video and also the DF-30/35 lack the cable managment holes which making me upset.
Anyway, the DF-85 is amazing case, imo its loosk ugly at photos but in real life when you really have it, you realize how awesome it is.
For more philosophy, once you have a DF case (especially the DF-85) it will be hard for you to switch to another case, since the unique features that look like a gimmicks are actually very handy.
