First up are the removable 5 1/4" drive bays. As mentioned earlier, each bay holds three devices (optical drives, fan controllers, removable HDDs, etc.) and is held in place with four thumbscrews. The bays are powder coated Sky White to match the rest of the chassis.
Next up are the removable motherboard trays. Each tray has two 80mm fan ports, an I/O slot and seven expansion card slots with reusable covers. The two motherboard trays are virtually identical except for the lip that extends out at the bottom corner. This lip lines up with a screw hole on the inside of the case and is secured with a single thumbscrew.
Here we have the 5 1/4" aluminum drive bay covers, which are also powder coated Sky White. The quality and construction of these bay covers (and all of the modular pieces thus far) are top-notch.
