NZXT Tempest Reviewajmatson -
The NZXT Tempest has plenty of room for expansion. The case has enough motherboard space to accommodate ATX, Micro-ATX, Baby-AT, Flex ATX, and Extended ATX boards. The motherboard tray is not removable however, so work space on the inside might be cramped if you have large hardware. Also, you'll notice that the motherboard tray has cutouts for easier cable management and better air flow.
The amount of available drive bays is incredible - there are three 5.25" external drive bays, and one has a 5.25" to 3.5" bay converter for floppy drives or other 3.5" devices. The Tempest also holds an impressive eight 3.5" internal drives in a server-style configuration, with the drives stacked on their sides in two cages - each holds four drives. These cages can be removed to add more 5.25" devices, if needed.
All of the drive bays use a tool-less design for installation and removal, unless you install a 5.25" drive where one of the hard drive cages used to be. The 5.25" drives use a latch that acts like screws, and the hard drive cages use a rail-type system to hold drives in place.
There are the seven expansion slots on the Tempest, which allow you to add expansion cards and other expansion port devices, which allows you to add a USB bracket without taking away any card slots. Above the expansion slots, there's a 120mm exhaust fan for pulling warm air away from the CPU and regulators.
The Tempest also has two radical new features. First, NZXT has chosen to place the power supply at the bottom of the case, which keeps the hot air from the PSU from mixing with the CPU and raising critical system temperatures. The one problem you may run into here is with the 8-pin CPU power plug - you have to be creative in your routing to get it plugged in and not have it interfering with the expansion cards in the process. Second, NZXT has included pre-drilled holes and space in the top of the case for the installation of a liquid cooling radiator - this makes turning your rig into an overclocking monster even easier!
