The guardian sports well-defined lines that help give it an aesthetically pleasing exterior, without being gaudy and overbearing. While the case features a fairly prominent lighting, the overall design helps keep the Guardian from appearing to be a rejected idea for a transformer. The case itself sports blue colored fans on both the front and side, and the front grill gives it a mean appearance thanks to its scowl-like facade. On the top you can see the blue-tinted LCD temperature readout which is useful for monitoring how well your cooling is holding up, especially under hard overclocks. The side window glows from the LED powered fan, helping to show off what you have under the hood.
Behind the front door, you will find three 5.25" drive bays and 2 3.5” floppy disk bays. Above the 5.25" bays is an embezzled badging for NZXT and at the very bottom is the grill for the front fan. The door is fairly light and has strategically placed magnets to help keep it closed. The exterior is painted in a matte black, while the plastic door has a glossy veneer that provides a sharp contrast to the rest of the case.
