Antec Performance TX640B

Examination:

Compared against the other Antec Performance TX products, the 640B remains virtually similar when it comes to the side panel, case features, and TAC (Thermally Advanced Chassis) compliance. Unlike the 1050B and 1088AMG models, the 640B comes equipped with no front panel door. Measuring in at 440 x 206 x 472 mm this 1.0mm SECC steel chassis has support for three external 5.25" and two 3.5" drive bays. Contained on the inside of the chassis are three internal 3.5" drive bays. Beneath these external drives in the center of the case are the front panel I/O connectors. These ports are two USB2.0, one Firewire, and two audio jacks. Also on the front bezel are the power/reset switches and respective LEDs. To assist in the prevention of dust from entering the system, Antec has placed a washable fan filter to cover the two front intake fans.

Unfortunately, the dust filtering used on the front of the chassis isn't brought fourth to the side panel. To comply with the TAC (Thermally Advanced Chassis) specifications, and to assist enthusiasts in cooling their systems, Antec utilizes two fans on their side panel, one of which is a 92mm mount focused on the CPU socket area and the second is an 80mm interface designed for the video card/expansion slots. In addition, the fan grills used on the system aren't very restrictive when it comes to the airflow but we found this to assist in a greater build-up of dust. Keeping the side panel secure is a nice dual-locking system while the top lock actually contains a key for minimal security purposes. On the rear of the chassis are simply the standard features expected for an ATX chassis, along with a 120mm exhaust fan, and an Antec 400 Watt SmartPower 2.0 power supply. Although the PSU would have a difficult challenge adequately supporting a SLI or CrossFire system, the included power supply is nice for general usage and definitely better than what other manufacturers bundle.

Taking a look at the inside of the Antec chassis, it faintly reminded us of the Chieftec days due to the near tool-less design and removable drive cages. At the front of the case are the drive bays along with the two 80mm fan mounts, which are protected by the previously mentioned fan filter. Thankfully, both of these fan slots utilize tool-less mounts but the remainder of the case fans require screws. Overall, the innards of the case are normal compared against similar ATX cases when it comes down to its traditional mounting methods.
