Your Ideal Silent Case

The P100 is an ATX case that epitomizes cool, quiet, and sophistication. It features Antec’s award winning Performance One series design and Quiet Computing™ technologies that minimize system noise.


Features and Specs

Flexibility and Functionality

In addition to 7 expansion slots, the P100 also supports 2 tool-less 5.25” drives and 7 tool-less 3.5”/ 2.5” drives. The front panel swings open 270 degrees to reveal front filters and drive bays while keeping the design sleek and professional looking. As with all Antec enclosures, the P100 is engineered with Quiet Computing™ Technology, and stands in a class of its own.

Engineered For Quiet Computing™

With a great price to feature ratio the P100 is the only economical case that delivers first class silent performance. A balance of price and feature is achieved by integrating Antec design with superior build quality. Engineered with Quiet Computing™ Technology, the P100 is truly in a class all its own. It includes all the features of a premium chassis including a dual layer construction on all panels with silent fluid dynamic bearing fans.


The P100 offers new levels of convenience with a total of 9 tool-less drive bays, a CPU cutout that allows for easy heat sink replacement, and a double-hinged front door that opens to 270 degrees. The P100 also features USB 3.0 support, rubber grommet ports on the rear to allow builders to easily mount external water-cooling hardware, and cable management behind the motherboard tray to reduce cable clutter.
