Antec Three Hundred Two Midtower Case ReviewWed, Mar 14, 2012 - 12:00 AM
Looking Closer at the Three Hundred Two
The Three Hundred Two is a mid tower chassis. Its overall looks are not too aggressive, and just ever so slightly updated from the original Three Hundred. The sides of the front bezel have a slight outward curve to them, where the original was straight. The left side panel still has a mount for an optional user installed 120mm fan.
The front I/O has been updated as well. The arrangement is the same, but the USB ports have been updated to be USB3. So left to right, two USB3 ports, Audio ports, reset button, and power button.
The top rear of the case still has a 140mm exhaust fan. What has been changed is the fan has been updated from the old 3 speed TriCool 140mm to the new 2 speed TwoCool 140mm fan. On low the fan pushes 33.6 CFM @ 21.8 dBA, on high 58.9 CFM @ 26 dBA. Antec also decided to add water cooling pass through holes to the Three Hundred Two, something that the original did not have. For the life of me I do not understand why they put them on the top rear left corner of the case, rather than on the back where they are typically.
On the lower left of the case Antec gave the Three Hundred Two the side accessible PSU dust filter that they introduced with the Performance One P280.
On the right side panel Antec added the 120mm fan mount behind the CPU socket.
On the back there are a couple of more updates. There are now 8 expansion slots and the speed controls for the rear and top fans can now be accessed from outside the case.
To gain some room inside the expansion slots are flush to the back of the case. The retention screws for the expansion cards are now outside the case.
So there is room for installation of the cards a large slot is in the back of the case and covered with a cover plate. Not really a security feature as the plate is attached from the outside. It is mainly to cover the slot in the back of the case.
On the bottom of the case are the stick on style rubber feet.
