I have both the Silverstone Raven 2 and the NZXT Phantom and they are both very good cases - very little to choose between both of them though the Raven has the edge on cpu/graphics cooling. Here is my thoughts on both:
Silverstone Raven 2
Very sleek and elegant case that does look great until you start adding opticals and what not in the 5.25" drive bays - then it can lose it's luster quite quickly.
Performance is top notch with the unique motherboard orientation it will keep all your components comfortable and effortlessly cool even in this heat.
Plenty of room to work and great cable management.
Runs quiet or near silent depending on your choice of fan speeds.
Limited 3.5" hard drive bays (3) and limited access to them and the 5.25" bays once everything is installed.
Would personally seek out the Raven 2 Evolution which has redesigned and better (more) drive bays + the air penetrator fans making it the almost perfect performance case with the exception of usb3.0 ports
NZXT Phantom:
Build quality really surprised me on this one - it may have plastic but everything feels and looks like a solid quality case inside and out.
Lots of rubber mounts to stop vibration in both the drive bays and the psu area.
Cable management is superb and very well thought out.
Again depending on what mode you want to run - it can be made pretty much silent without giving up too much performance.
Only drawbacks I can find with the Phantom are that I would go for the white chassis as finger prints etc. really show up on the black case. Not great if you are like me and like to utilise the top of the case - why they didn't just make parts of it flat and give up a bit of design flair is kind of stupid.
As I say if you can seek out the Silverstone Raven 2 Evolution and don't plan to spoil the look of it by filling up the 5.25" front bays it would just shade it for me over a white NZXT Phantom.
