Corsair went back to the drawing board and improved that 400R model towards an updated SKU, the 500R.
They added more meshed vents, a new 200 fan was added, a three step fan controller and tweaked the overall design a little as well with removable and relocatable hard drive cages allowing you to even insert a 452mm in length graphics card. But wait Dave .. there's more.
