Up for sale is an internal bracket for 3.5" hard drives for a Corsair Graphite 220T RGB computer cases. This made out of steel painted white and it holds 2 x 3.5" drives. You will need to provide your own mounting sleds for the drives, but the screws to hold the cage into the case are included. The last picture shows how the bracket fits into the case. Hope someone out there on the internet can put it to use! It also might be useful in your own custom creation - it measures about 4 1/2" tall (including the tab) x 6 1/2" deep (also including the tab) x 4 1/2" wide and is made of steel and painted white. The tab sticks out about one inch.
This may fit other cases, but we're not for certain - you should check with Corsair for compatibility with your case BEFORE you purchase this one.
