Product description Product Description

Carbide Series 300R Mid Tower Case, 2xFront USB3.0, Supports Mini-ITX/MicroATX/ATX/E-ATX, 7 PCI Slots, 3x 5.25in Bays, 4x 3.5in Bays, Max GPU Length 450mm, Front 2x120/140mm, Top 2x120/140mm, Rear 1x120mm, Side 2x 120/140mm

From the Manufacturer

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.

The front panel includes two USB 3.0 connectors and audio connectors.

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.


High-performance gaming systems need room to work with. The compact 300R delievers the room you need to build your ultimate gaming PC.

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. All the bays all tool-free, and the hard drive bays have integrated support for 2.5" drives, so you won't need to deal with adapters when installing SSDs

Build quality.

Whether you're building multiple systems or just one, and whether you're a professional or if it's your very first build, the 300R has the smart features that matter. Just like the drive bays, the side panels are tool-free, so you'll spend less quality time with your screwdriver.

The black painted interior has a CPU cutout for quick installing or upgrading of CPU heatsinks, and Corsair's innovative cable management system provides a straightforward way to route cables behind the motherboard, not across it where it can interfere with airflow and give your system a cluttered look.
