Corsair 800D has two 3 ½” hard drive bays located on the power supply compartment and a removable plastic lid separates these bays from the power supply compartment. Another two lids are available, one covering another 140 mm fan in charge of cooling down the hard disk drive cage and another covering the hot swap connectors. Compare Figure 13 to Figure 14 to understand.

Notice how there is a hole near the hot swap connectors, so you can easily route the cables while keeping the lid closed for better aesthetics.

An optional 120 mm can be installed on the lower hard disk drive cage.

In Figure 15 we have an overall view from the motherboard compartment. Daughter boards are fastened to the case using black thumscrews, which is great.
