First off, we have some full frontal action.  On top, we have our I/O panel, with four USB, one Firewire, and one eSATA port for data transfers, as well as a headphone and microphone jack to handle the audio.  Just below that, we have our six 5.25" bays, with the bottom bay serving dual purpose, as it can also be converted to 3.5" as well.  Underneath that, is one of the three 230mm fans, this one glowing a nice red under power.  

The case is constructed primarily using steel with plastic accents, including the front panel.  Steel in a case this size means sturdy, but also quite heavy.  I am not a huge fan of plastic on cases, however, it is obvious in this case that this is no cheap-o plastic.  The whole case oozes rugged. 

Here is a closeup of the I/O panel.  To the right of the I/O ports are the Power and HDD activity indicators. 

Next, is a close-up of the optical drive bays.  On each side is a tab that can be squeezed to release the panel cover.

On top of the HAF are the power and reset switches, adjacent to the easy access fillport.  The fillport is capped off with a flexible rubber mat. 

Behind the fillport on the top of the case is the second 230mm fan.  If you look closely, you can also see that there are additional screw holes; what this means is that you can swap the large fan for three 120mm fans, or, even better, a 3x120mm rad.  Note that two of the screw holes lie in the fillport bay.
