Well this is a plan for a case that i hope to start building soon. This will be my first build and my first time designing one, so i hope some more experienced people will be able to give me some pointers. I plan on constructing the frame out of aluminium angle and then using sheets of aluminium for the panels. The motherboard tray i plan to make out of acrylic and this will be raised from the base of the case to provide some cable management options. The parts in these images are only used to show the placement of the components but i tried to use similar sized components.
