The Antec NSK3480 ($100) is a mini-tower computer case that accomodates micro-ATX motherboards only. It is essentially the smaller version of the Antec NSK4480 ($100), and is the successor to the Antec NSK3400 with the addition of a 380 Watt EarthWatts power supply that meets the 80 PLUS certification. Other than its smaller size (click here to compare the two cases in 3D), the NSK3480 also features a dual-chamber design that separates the power supply from the main case with a physical barrier to isolate the heat and noise from the two spaces. It features a 120 mm rear-facing case fan, and top vents for the PSU chamber.
