That depends on what you want to achieve with your new build ;0. Silverstone Ft 01 probably won't hold you back too much, unless you are intending on going for an EATX motherboard.
However you are spoilt for choice at the moment for standard ATX cases, a few goodies: Fractal Define R6, NZXT H500i, Phanteks 350x, Phanteks EVOLV ATX etc. It all depends on whether or not you would like a window case or are you going for a quiet under the desk build?
Cheers.
