The BLACKSTORM case makes assembling a system easier than ever before. It has a modular, tool-less design that makes the initial build and future upgrades easy. Both side panels latch into place for easy access. If you are a big fan of Smilodon then you shall never miss Blackstorm, the latest version of one-click side panel case. A 120mm fan is mounted on the front of the case to draw cool air in and blow it across the hard drives. Side/180mm optional and rear mounted 120mm fans keep the air moving over all critical components. Keep it cool and keep it functional.
