I have attached a file used by me in the laser hive for front panel conversions in some of the G4 models. This template is for the early G4s to trim the front of one of the Corsair Obsidian IO panels and give firewire, USB 2.0, 3.0 and front audio. I have decided to release this for general non-commercial purposes. The pdf shows what it is, and the dxf is the cutting profile. Hope you find this useful and you can even use it to hand cut if you want (!).
