This panel conceals a multi-format card-reader (they just built in a ready-made device of the 3.5?form-factor) and the typical selection of connectors you can find in any modern system, namely USB, FireWire, headphones output and microphone input.
An interesting design detail that immediately draws one’s eyes is the vent opening in the top panel opposite to the CPU socket.
We’ll talk below about the effect this vent opening has on the temperature of the components. A nice thing about the top panel is that there is a strip of soft material glued around the panel’s perimeter on the inside.
Rattling of the panel is prevented, and it is also a pleasure to put it down ?there’s no that metal-on-metal sound and it feels like you’re dealing with a well-made top-quality thing.
