It's pretty easy to install the drivers when installing the OS. No need for extra hardware, especially if you don't build computers that often. Just download the mobo drivers, and while you're at it, gpu drivers and save them to a USB drive. Then when the OS install is looking for a network, press Shift-F10 to open a command prompt. CD to where the LAN driver is and run it. It will install the driver and you can continue with the OS install.
