This is the basic layout for our briefcase build.  Above you will see the bottom section of the briefcase with the main parts/part assemblies outlined.  Aside from the space in the front, separated by the black divider, this section of the briefcase will be covered by an acrylic layer to help direct airflow and to prevent major spills on to the components.  There will be two fans to cool this system, not shown in the drawing.  One will be placed above the PSU (4) exhausting up through holes in the acrylic layer and the other is integrated in the the CPU cooling which is in the main computer assembly (1) and will be intaking air.  This should pass air through the system cooling the main components first and then moving to the side before exhausting.  This image does not show the smaller cable runs but does show the main power lines (Purple lines), as those are very thick and will have to be accounted for when planning out the components placement.  The main computer assembly (1) includes the Motherboard, CPU, CPU Cooler, RAM, and SSD.  They all fit onto the motherboard and so they do not need to be shown individually, just as one big part.  The next large component, moving to the left, is the PCI E riser cable (3).  This is the cable that is required to turn the GPU (2) sideways so that the fans can be exhausting up to help with airflow.  The final main component in the system is the PSU (4) which will be the tallest part of the system, and so we will likely have to remove the casing from it.  This is the basic layout for the bottom of the briefcase, the rest of the components are either apart of other larger parts, or they are so small that they do not need to be shown.
