The RAVEN RV02-E is an evolution of the original RV02 case that aims to provide even more accessible performance and utility. Making a debut for the first time in a tower chassis, SilverStone's own Air Penetrator 180mm fans are included in the RV02-E for improved air intake efficiency and flexibility. The fan frame of the Air Penetrator fans provide enough fan blade protection and increased air focusing ability that they no longer require installation of fan grille. Hot-swappable hard drive cage was also implemented to facilitate installation at the expense of losing the 8th expansion slot. However, all other features are intact such as fully filtered intake system, 90 degree motherboard mounting, all black interior, liquid cooling support, and fan speed switches. For enthusiasts not looking to use more than two or three graphics cards, the RV02-E should be a great alternative to the fantastic original RV02.
