Adding internal USB hub

I was wondering what kind of work woudl be involved adding a 4 port USB hub to my Acer Aspire One D150. I would like to put bluetooth, gps, and a dedicated 2gb stick for readyboost. I realize this will take some soldering, but just wondering if anyone has done this and what the process was like

The circuit boards on computer systems are highly integrated - they're assembled and soldered using automated equipment. It's pretty close to impossible to modify them. Even if you have access to the very specialized equipment used to deal with surface-mounted hardware, the best you could probably hope to do is to replace a faulty component.
