EVERYTHING YOU NEED, NOTHING YOU DON'T. A COMPACT EXPRESSION OF CORSAIR'S GAMING PHILOSOPHY. Great systems start with a great case, and Carbide Series 300R provides a remarkable number of features in a compact chassis. Easy access, lots of room for expansion, and superior cooling make the 300R a great choice for building powerful PCs that don't take up a lot of room. SERIOUS COOLING POTENTIAL. The 300R is equipped with two fans for intake and exhaust, and the integrated dust filters on the front and bottom intakes are easy removable. There's room for you to install five more fans, including mounting points for two side panel 120mm fans for drawing cool air directly over your GPUs. If you're building a multi-GPU gaming rig, proper graphics ventilation is essential. IT'S BIG WHERE IT COUNTS. Despite its size, the 300R can fit extra-long graphics cards of up to 450mm length, and it has three optical drive bays and four hard drive bays.
