The Phantom was due for an overhaul. It was great, and still is, but as demands of consumers change and the industry shifts, there's always room for improving. Why would we just let the Phantom, one of our best selling cases (and one of the most modded cases out there), sit stagnant?
The new Phantom is rebuilt from the ground up, and is a huge evolution in the Phantom line.
Man, i just got a regular phantom probably 4 months ago.. I would consider getting this new one, but i did a bunch of mods to mine.. if it doesnt blow me out of the water, definately a contender for my next case. The phantom is a sweet case.
