I started to add some models to the interior of the deck to determine orientation, spacing, available room, etc...

So far I've added two blocks to represent the USB hubs which are based on the advertised dimensions. I've added a block for the battery pack I have based on my measurements. I've added a placeholder block for the HackRFone card based on my measurements and a fully realized 3D model for the actual Pi. The USB ports are approximated with a model I found that had the same footprint, so I replaced the arcade button assemblies with those. I've reduced the number of rf/antenna ports to just what is needed for the sdr dongle and the hack rf one and placed those near the top assuming antennas will want to be higher and the connections usually lead upwards.

I was thinking of just leaving the cubby hole for the battery pack open and just slide the battery in and out. I also need to add power ports to the front panel still.

I've also accounted for the pi camera board size and sketched that in. I still have hope in include the 2nd monitor so I am brainstorming how I can make that happen.

So far I'm feeling good about the space but I haven't modeled any wiring so it could get ugly fast.:)
