Hello Mr Chooks
Well just to clear one thing up SATA drives have no "Master/Slave" relationship. They basically install as say SATA 1,2,3,4 ect
another thing to note is the new boards only have one IDE slot so I personally don't think it is worth putting a 20G IDE drive on the same slot as your DVD. If you feel you need another drive just buy another sata drive, that board has ample SATA points. Storage is cheap, a 80G SATA drive is about $65
Personally I would go for a E8400 or a E8200
The CPU you have chosen is basically already outdated and the E8XXX are not really more expensive. Best to buy current stuff.
Honestly, do yourself a favor and get a better video card, the 8400 graphics series is the bottom entry level in cards and really has no punch
look at something like this, it's not over the top but still has some decent performance

I am not sure where you are in OZZ but if around Sydney compare some prices with this site. I have used them a bit of late.

You may find you can save yourself some cash and get better components for the same price you are going to pay now.
