Why has nobody mentioned the Silverstone TJ-07? I am getting this case when I do my first build in 4 months. It is one of the top cases on the market and is one of the best in my opinion.
I have the Antec Sonata II as well and its only moderately ok. I only bought it because it had a decent PSU and it was an upgrade from the first one which my dad has. I think its a wee to small though for my liking. I also have 2.5 feet of cathode in it, 2 120mm blue LED fans and a fan controler. The blue LEDs in the front where annoying so i just coverd them w/ some black tape
Everyone is entitled to their own opinion, but I and many others love the style and design. I guess you prefer the box type rather than something a little more original.
I love my case, the NZXT Lexa. Not over-the-top flashy, but looks great and has great cooling. I was going to go for the NZXT Nemesis at first, but I think it's just a little too fancy and the Lexa is more stylish.
