Top and Bottom Panels

In Figure 5, you can see the top panel from ATCS 840. This case comes with two 230 mm fans there (180 mm blades). The small panel containing the audio and USB connectors is hidden and you need to press it to have access to these connectors.

This case comes with four USB ports, one FireWire port and one eSATA port, the most perfect combination possible. The USB ports are separated in two sets and each set is distant enough from each other allowing you to install two “fat” USB devices at the same time. The two ports within each set, however, are too close to each other.

The bottom panel from this case has some features as well. In Figure 7, you can see the air outlet from the power supply on the left (features a washable dust filter accessible from inside the case) and the washable dust filter for an optional 120 mm fan that can be installed on the bottom of the case (doesn’t come with the product).

The feet are very stylish, looking like the ones used by audio receivers.
