Now its time for a update:
The theme for this mod is based on the Asus Rog Xonar Phoebus sound card and we will invert the motherboard tray so will be the first thing we see from the top window from the case.
Here some render test made by Hardmodding:
The inverted motherboard tray that is the same length as the case
The midplate as the same lenght as the mohterboard tray
The side panel and the top panel
The front panel
