hmm.. the sliverstone is only 15bucks more so defintily a option. how does the nzxt look in real life?
Exactly it does in pictures you see online actually. the build quality is very good. certainly a stunning addition to any gaming room. I get many compliments from friends, even works on non-geek girls haha.
my main complaint is that the top and front panels are plastic. they're high quality plastic, won't break at all, but still, plastic is plastic, and I love silverstone for their brushed aluminum look.
as far as performance, the NZXT is just about the same as your antec, if not a little bit worse, due to the antec having a much more linear fan set up (in the front, out the back). the two 120mm fans on the NZXT's side panel blowing at the HDD cages are a bit unnecessary and disrupts the front fan's air flow a bit. so I usually have the front 140mm blowing at full speed, and the side 120mms on low speed. there's nothing WRONG with the phantom, but it won't get you better case cooling than the antec if that was one of your reasons for the upgrade.
I recommend the silverstone raven because, well, if you want red, you can paint it yourself, there're many tutorials online to show you how. cooling wise it's a great design with bottom fans blowing cold air up (natural flow). the 90 degree mobo rotation also means your mobo's PCIe slots will be facing up. so all that hot air from your GPU's custom cooler that people complain about blowing around the case? it'll flow up and out of your case, because that's the natural flow of hot air
aside from that, the raven's quiet stunning to look at as well. at least in my opinion, and since I like the NZXT phantom look as well, I'm hoping our perception of beauty can't be that different
EDIT: a word of warning. if you do decide to get the raven 02, be aware that it's larger than the phantom or the antec nine hundred. if you don't have the space, there're other cases in the raven series that are equally good. of course, there's also the NZXT case that you wanted originally
