I wanted an internal USB flash drive, but did not want to open up the unit (other than the memory access door) or solder anything to the board. I wanted the mod to be 100% reversable, with no traces left at all, thus preserving the warranty. A tall order perhaps? Not as it turns out.
I was looking at my eee the other day (a new white 4g, without a flash connector in the memory bay), and pondered the 3 usb ports. Too bad, I said to no one but me, that one of those couldn't somehow be accessed from the memory door area; after all, I can't imagine using all 3 of them at once, ever. Looking at the ports on the right side, I noticed the two little metal tabs in the bottom of each port; through the small gap around each tab, I could see light coming through the vent under the wlan card. I wondered further whether four small wires could pass through the gaps around those little tabs, under the wlan card (or over it, if you've turned your eee upside down by now), and into the open flash bay. I tested with a bit of solid wire, and found I could easily guide a wire into the flash bay; there's nothing obstructing the path.
