You could search Molex, Samtec, Tyco/AMP, Digikey, Mouser, etc. for millions of different connectors that would work.
The datasheet for the connector should tell you how much current each pin can handle. The one in your link didn't though... I would guess around 1A per pin, so power alone would need 5 pins).
However, I suggest you either start with a real docking station for the laptop, or live with only 2 or 3 cables. With a USB hub and a USB sound-card you should have only Power, USB, and VGA to connect. With a USB VGA-Adapter you could get it down to only 2 (or even USB-only when the laptop is already charged).
