The Antec One Hundred has a couple notable features that make it stand out from other cases. This includes 8 expansion slots, top accessory tray and unique 2.5” internal hard drive installation. In terms of design, the One Hundred doesn’t really have a lot going for it. Other than a couple of fan grills on the outside, a perforated front bezel and the top accessory tray, the case is pretty plain looking.
Each of the drive bays on the front bezel has their own perforated slot covers, which are backed by foam for air filtration. Only the top 3 external 5.25” drive bays can actually be used; the rest are just dummy covers.
On the top of the front bezel you’ll find the quick access ports which include four USB 2.0 slots, HD audio mic/headphone jacks, and the power button; there is no reset button on this case. Behind the ports you’ll find a nice little tray which can hold your phone, keys, CDs, or whatever else you’d like to store there. Further back on the top of the case is the top 140mm exhaust fan.
The side panel is pretty bare and only includes the grill for the 120mm fan, which isn’t included.
The back panel of the case has a pretty standard layout. There are a couple of unique features on the back, this includes the 8 expansion slots (compared to the standard 7), as well as two fan controllers near the top, which allow you to stop between low and high fan speeds on both the top and rear fans that are included with the One Hundred.
The rear 120mm fan can be seen through the rear grill. None of the included fans have any LEDs on them, which may be a good thing for some and a bad thing for others. Both of the side panels are secured by two thumbscrews, making a tool free and quick side panel removal.
