Product overview



Standard Due date unavailable

The Carbide Series™ 300R windowed is a compact expression of the Corsair philosophy: great systems begin with a great case. Open the easy-access side panel to find a builder-friendly design with three tool-free optical drive bays and four tool-free hard drive bays with integrated 2.5" SSD compatibility. There's room for extra-long graphics cards, and the matte black interior really shows off your gear. Finish off your build with a cable routing system that keeps wires and cables out of sight and out of the airflow path for a clean, uncluttered look.

The 300R keeps your hardware cool with amazing airflow, including a 140mm front intake fan and a 120mm rear exhaust fan. There's room to add five additional fans, including dual side-panel fan locations that can deliver cool air directly to your graphics cards. And, the dust filters are removable for easy maintenance. Features like these make the Corsair Carbide Series 300R the foundation of your next great system.


  • Oversized, tinted window with room for dual 120mm or 140mm fans
  • Room for graphics cards up to 450mm long.
  • USB 3.0 front panel connectors.
  • Built-in compatibility for SSDs in the four hard drive bays gives you the flexibility you need.
  • Keep your system cool with up to 7 fan mount locations.
  • Easily accessible dust filters keep the cool air flowing over your valuable components.
  • Install or upgrade your CPU heatsink quickly with the easy-access backplate cutout.

5* Good quality, easy to use case...
Reviewed by Christopher on 24/09/2013
I bought this case for my first PC build. The build quality feels and looks good and strong. All the hardware I bought fitted perfectly without any issues and the design of the case allowed me to keep loose cables tidy. The fans provided are relatively quiet and the dust filter below the PSU is a handy feature. The LED's for the power button and the HDD are a bright white, which looks really nice. The only con of this case, as far as I'm concerned, is that the power button feels cheap.

Arrived today, first notice how light the case is compared to my old Zaltman GS1000plus. Feels tinny, looks good. Plain no frills, small, but not to small nicely set out inside, as described in adverts. Get to work prepare my mATX mother board for fitting. Screw 1st adapter nut onto case back plate (This is to allow the fixing of mATX to back plate.) FIT SECOND! oh, NO SECOND. So that's why it felt so light. 1 Adapter missing. Build stopped..e-mail..Corsair..stop..e-mail BT..stop..Hunt around my garage to see if I can find anything to do the job..stop..Wait a few weeks for an replacement, I hope..stopped..
