Building a new PC

So I'm considering building a desktop for myself since my laptop is all that I have and it's not quite able to do everything I'd like for it to. This endeavor will but quite interesting considering I have little to no experience with building a computer any input would be greatly appreciated.
Here is a parts list, I'm trying to keep the price pretty low as I am but a poor kid with not a lot of cash to spare.

Case w/Power Supply

Hard Drive

CD Drive

Processor

Motherboard

Video Card

RAM

In addition to these primary components I'll probably be purchasing the following:

FireWire Card

WiFi Card
