Yes, already ordered the system but it's still in production for a couple of weeks so I can still cancel it.
It is basically this system: http://configure.us.dell.com/dellstore/config.aspx?oc=dxdwps2&model_id=xps-8500&c=us&l=en&s=dhs&cs=19&link_number=17970622
It does have SATA3 6Gb/s connection and 4 USB 3.0 ports. For the price, I don't think I could have done any better on my own.
But then again, that's why I'm here.
