I'm back

I'm sorry for like stopping this, but I've gotten some money and now I'm seriously looking for one build.

Firstly, I've got 2 x 2gb RAM.

It sais: 2GB. 2Rx8. PC2. 6400U. 666. 13. E1. 800.
I only wrote that because I want to see if it is compatible with this rig im going to show you.

And I got a Intel Core TM2 / Duo SlapB Costa Rica 2.66GHz / 3M / 1066 / 063848A477
That's what it sais on the CPU

Now, I've been thinking about getting this rig.

GFX Card ($197.00): http://www.centrecom.com.au/catalog/prod...s_id=33359
Mobo ($107.00): http://www.centrecom.com.au/catalog/prod...s_id=37779
PSU ($119.90): http://www.centrecom.com.au/catalog/prod..._id=30877B
Hard Drive ($71.00): http://www.centrecom.com.au/catalog/prod...s_id=37086
Case ($53.90): http://www.centrecom.com.au/catalog/prod...s_id=37884

Total : $548.80

Now, that is without the DVD Drive.
I don't know what to do, like what cabels you need to make sure the DVD drive works, their is one cable that comes out of the PSU, right? And another that looks like this >http://www.centrecom.com.au/catalog/product_info.php?cPath=73&products_id=345 <

I have one of them, but would I need another? Like anything else to connect anything else together?

That's what I need to know from now, I'll ask more later.
