NSK4480 is one of the simplest cases from Antec, targeted to users that want to build a mainstream PC with a good 380 W power supply (this model comes with an Antec EarthWatts 380 W power supply already installed) and prefer having a smaller PC with a more conservative looks, but with a good construction, a 120 mm rear fan and side duct.
This case uses the traditional “mini-tower” size, with three external 5.25” bays, two external 3.5” bays for floppy disk drives and three internal 3.5” bays for hard disk drives. It also has a very conservative front panel, with only two USB 2.0 ports, on/off (“standby”) button, reset button and power LED. No headphone and microphone jacks are available.
On the side of the front panel you can find several holes where the air enters the case.
In Figure 4, you can see the rear panel, using the very traditional ATX design, but with the addition of one big 120 mm fan there.
