Computer parts advice

Hi, im completely new to the world of computer building etc and i desperately need some help!
I have a cousin who has recommended some parts and this is the list that ive got so far...
Motherboard http://www.overclock...rodid=MB-237-GI
Processor http://www.overclock...rodid=CP-259-AM
Memory http://www.overclock...rodid=MY-086-GL
Graphics Card http://www.overclock...rodid=GX-219-SP
Power Supply http://www.overclock.......7-AN&tool=3
Hard Drive http://www.overclock...rodid=HD-067-HI
Extra Cables http://www.overclock...rodid=CB-010-AK
Speakers http://www.overclock.......0-LG&tool=3
DVD drive http://www.overclock...rodid=CD-101-LG
Network card http://www.overclock.......9-BE&tool=3
Case http://www.overclock.......2-XG&tool=3

I already have a monitor, it isnt widescreen but square in shape. It is flatscreen though. I also have my own keyboard and mouse already. I can probably stretch my budget a maximum of £50 more to about £680 as this is my first one and i intend to upgrade as i get more money (im still in school). Are there any parts that will be completely awful? Also, I will be using Windows 7 64 bit and i intend to be running small animation programmes on it.
Thanks for your help
