See sig for specs...Everything is coming today except the 250GB hard drive. I am going to proceed with the build, but my question is this: I've never dealt w/ SATA drives before, and my understanding of them is that you have to install the drivers when installing Windows. If I build everything and install Windows, then the drive comes in two days how will i get it to be recognized by Windows? Will the drivers already be there so it is just a plug and play? Let me know what you guys think. Thanks.
