This modification for Antec P183 and P193 cases allows use of a USB 3.0 bracket (modified) to provide internal USB 3.0 connections for the front panel port. Note that it requires that the motherboard in the system have an internal USB 3.0 header and include a bracket as well; the upper drive bay also has to be left installed, so cannot be used in tandem with some liquid-cooling and quiet modification packages.
Configure a custom computer with the USB 3.0 Pass-through Cable to Internal Header Mod (for Antec P183/P193).
