57: The side panel mod is coming a long nicely. Made my holes using 3mm drill bit for the perforation and 4mm drill bit and 4mm self-screwing fan screws for the mounting holes. Not sure I will actually use the acryllic side panel as it is mostly a view to the PSU, but I am committed to perforating the acryllic and at least trying it out. Note that this picture was taken prior to the 55-56.
