SilverStone RVZ01-E is an evolution of the ground-breaking RAVEN Z RVZ01, a slim form factor case with tremendous capability. While maintaining the same volume size and appearance as the original model, the RVZ01-Es interior was reworked to convert SFX power supply space into one for standard ATX (PS2) power supply. This amazing change came with little sacrifice as the case still has support for the biggest consumer graphics cards on the market with superb air cooling performance. Designed for use in either vertical or horizontal orientation, it can be placed comfortably in any space-constrained environment that requires a powerful PC. For those looking to build a slim form factor PC, the RVZ01-Es ability to accommodate standard ATX power supply will help to open up more flexible and varied assembly option.
