If you are a seripus gamer you need a good mid tower. I suggest getting an Antec nine hundred black Steel ATX Mid Tower Computer Case. This mid tower case is a quiet running case and it can hold all the power you need to run all thsoe cool games you want.
The 5.25″ bays will hold optical drives, burners, or even (gasp!) your aging floppy drive, and up to six 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 window into the case, in addition to letting you show things off, provides additional ventilation, either by way of the vented screen, or by the fourth fan in the box, mounted into clear plastic, for a clear and elegant mounting. 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!
