The CM storm has a ton o' features (fan controller, hot swap, rotatable HDD mounts) -- but at that price I would just gather a few extra clams and get something with a little more flexibility in fan mounting.
I currently own a HAF 932 -- It was a good case (switched to Corsair 600t) Great airflow, Great fan/Rad mounting
only thing is the case feels a little bulkier than most, being able to top mount the PSU inside the case makes it a little tall.
Carbide 500R is a good choice, with ample cable management slots and grommets it's got good potential and future proof-able. It is a little on the ugly side, but with a little getting used to it'll make a great case.
The INWIN GRone has few good features, silent/turbo mode fan profiles, hot swap dock on the top. But the construction of the case looks a little flimsy and cheap.
NZXT phantom 530 is the same price as the INWIN GRone, sleek white case style, slotted fan mounting holes for greater placement optimization.
BitFenix however, An attractive looking case but with the features it offers it's just not worth the price. Minimal fan mounting spots, not very many cable routing holes.
