With the side panel removed we can see the fan used has a solid black frame and white blades despite offering blue LED illumination. The power lead to the fan offers plenty of length and ends in both 3-pin and 4-pin connectors. An accessory box included with the Lexa S has a fold-out installation guide, a collection of motherboard standoffs and screws, a number of thumbscrews for mounting optical and floppy drives, five sets of rails for mounting hard drives as well as a 3½" to 2½" adapter to hold up to two notebook-sized SSD drives.
The holes for the power supply only allow it to be mounted facing one direction. The motherboard tray is surrounded by slots with rubber grommets and thin punch-outs for cable management. A large opening behind the motherboard CPU socket will allow the backing plate to be changed without removing the board from the tray. Riser slots have mesh filler plates held in with screws. The exhaust fan is similar in appearance to the side panel fan however it does not have the blue LEDs.
There are four 5¼" drive bays and two 3½" bays, all but one of which are available externally. One of the 3½" bays is blocked by the front panel fan controller knobs. An additional five 3½" drive bays are positioned at the bottom of the case, turned 90° for easier installation. The rail design for these lower bays places the power and data connectors at the opposite side of the case where they will be hidden from view through the side panel window. A 120mm intake fan is hidden in front of the hard drive bays.
Either two 120mm or two 140mm fans can be mounted at the top of the case, and one 140mm is included. Although due to the closeness of the motherboard tray and front 5¼" drive bays, another fan and/or especially a radiator may not fit due to interference with other components. The motherboard tray has an oversized cutout to allow access to the bottom of the motherboard after installation. This makes changing out the backing plate easier such as to install an aftermarket cooler. The front bezel detaches with a quick tug at the bottom, although it is somewhat restricted by the multitude of wires holding it to the chassis. The mesh filler panels are easily removed from the rear of the bezel in order to install drives, and the intake fan can also be accessed in this manner. The fan includes a mesh filter that must be unscrewed to remove, which complicates the cleaning process somewhat.
Next let's get some hardware installed into the NZXT Lexa S.
