The inside of the front of the case reveals that both the hard drive hot-swap cage and front I/O panel are removable. These can be relocated to any vertical position in the nine available drive bays. Only one of the CP05 hot-swap SATA drive modules comes with the KL02. It includes a built-in SATA cable and power wire but they have used standard Molex for power rather than a SATA connector. Two years ago this would be a good thing as many power supplies of the day did not come with SATA connectors or did not include enough, but most units today provide plenty of SATA power connections. At least the connections are pass-through, so if you add a CP05 hot-swap module for each bay you'll still only need one Molex connection to power the whole cage.
The 5¼" drive bays have tool-less clips that can be unscrewed and moved to another position if desired. At the front of the motherboard tray there is a rubber-coated clip for wire management which should come in handy for holding power supply cables. There is no path to run cables between the drive bays and the motherboard tray, it is a solid piece, however there are several holes in the tray itself to use as a pass-through if needed.
Next up, installation.
