Inside, the RL01 chassis also isn't too bad for it's sub-$50 price tag. There's five accessible 3.5" drive bays, each with a tool-less mount on the left side. These bays are also rotated 90 degrees for cleaner cable management and more space for long video cards in the main area. A single 120mm red LED fan in the front of the case will provide cooling to your drives. This is the only fan included with the RL01.
There are elevated mounting holes for a 2.5" drive/SSD on the bottom of the case below the bottom 3.5" drive. Be sure to avoid 90 degree cables here though because the drive will sit almost flush with the bottom of the case.
Above the 3.5" bays are the 5.25" drive bays. Only two tool-less mounts are included for these bays, so you'll have to screw the remaining devices in by hand.
The motherboard tray doesn't have any pre-installed mounts, so you'll need to screw in mounts where required for your board. I was pleased to see the large CPU backplate cut out here though!
Some basic metal clips can be seen around the far edge of the motherboard tray. These will help with some basic cable management, but they're very flexible so don't overload them or they'll likely break off. There isn't any room behind the tray for cables either, unless they're extremely thin cables (not power or SATA cables).
