Do I have to use an Internal CD/DVD or can I use an External CD/DVD to

Hi,

When building a new system, can I use an External CD/DVD drive to install an operating system onto the computer? I mean will the BIOS give me the option to load a DVD from a USB device on the GIGABYTE GA EX58 EXTREME motherboard?

I'm asking cause I don't want to have to buy an internal CD ROM drive.

This computer is only going to be for playing World of Warcraft and a few other games.

This is what I bought from newegg to build the system:
Motherboard: GIGABYTE GA-EX58-EXTREME LGA 1366 Intel X58

CPU: Intel Core i7 920 Nehalem 2.66Ghz LGA 1366 Quad-Core Processor

Video Card: EVGA GeForce GTX 275 896MB

RAM: Corsair 6GB DDR3 SDRAM 1333 Triple Channel Kit

Solid State Drive: OCZ 60GB SATA II MLC Internal

Monitor: Acer X233 23" 5ms HDMI Full 1080P Widescreen LCD

Power Supply: XCLIO Great Power 850W ATX 12V/ EPS 12V SLI Ready 80 PLUS Certified Modular Active PFC

^_^

Yes you can!!
