Today I have desoldered the rear usb and ethernet and the front memory card plugs. I als hot-glued some terminals so they dont come loose or short. I also soldered 3 wires for +5,+12 and GND for the screen. I was not sure if the xbox power adapter would be enough to power the screen but when I tested it it ran perfecly. I also bumped the resolution upto 1080p and the tamps didn't go over Celsius! Here is a Link to the test video on youtube:
