Build it yourself.
Drivers are absolutely no issue
Use a different computer to download drivers from your motherboard manufacture's website and Graphics card manufacture's website
Save these files onto a USB
When you install windows onto the PC, plug in the USB and double-click all of them
As for building, just follow a LTT tutorial, really not hard. Nothing has changed as per hardware installation for AGES.
Someone else might have said this already, I'm too lazy to read the rest of the comments.
