as the header says just a quickie concerning the windows operating systems on the pre built gaming rigs..as i'm browsing through the configurations on some of the systems i notice there's no optical drive included (optional)... so here's the thing, how does the windows you pay for get put on the rig...is it through a pre embedded partition on the hard drive..like on some of the modern laptops these days..or a usb type install..its bugging me how the windows gets put on without a cd/dvd drive ?
