  • 2 x USB 2.0, 1 x eSATA, HD Audio I/O Front Ports

Ultimate gamer case? Just maybe. With a partially perforated package that finds room for six huge yet quiet fans, you have a seriously cool gaming case, and that's no joke. You expect the Antec Twelve Hundred 750 to be ready for lift off, especially with the 200mm Big Boy 200 LED fan and perforated port atop this stylish case. Contrary to some expectations, this case is very quiet, unless you have all the fans going at their highest settings, at which point you might hear . . . something.
The 5.25" bays will hold optical drives, burners, or even (gasp!) your aging floppy drive, and up to nine 3.5" drives can be installed in cages behind the fans, and these can be arranged along the front any way you like. This case provides a plethora of possibilities, and room to explore placement of all the pieces. The PSU, in a departure, is at the bottom of the case, for better case stability and thermal environment for the CPU.
The side panel plastic window, in addition to letting you show things off, provides additional ventilation, either by way of the vented screen, or by an optional 120mm side fan. This is a sturdy case built of steel, with enough cooling technology to keep things frosty in the hottest action. Take one home today and build yourself the "coolest" rig around!
