Asus Eee PC X101CH is an amazing netbook. It is fanless; look good (despite not having the new Eee flare design); has good built quality but is a nightmare for a normal user who wants to upgrade the hard disk; swap it with SSD or upgrade the RAM. To get access to HDD, you will have to disassemble the whole netbook. Also, the RAM is soldered to the unit and thus, there is no way to upgrade the RAM.
Folks at liliputing have posted several pictures on how to get it done. Basically, you need to unscrew the 11 screws that keep the unit sealed. After removing them, remove the keyboard. [via liliputing]
