Dell has published several illustration photos with description of how to disassemble the Dell Mini 10 and gain access to the HDD, CPU and Wireless card. Please note that you will have to take keyboard out in order to get your hands on the aforementioned items. And by removing the trackpad assembly, you can even add TV tuner to the unit. Unfortunately, you cannot upgrade the RAM as it soldered to the unit. More pictures:
