E7400 Wolfdale is pretty much identical, and is actually the one I was going to recommend, but the 7500 was a bit faster...2.93ghz compared to 2.8ghz so you are good to go there. (I was going off your high budget of $500-$600 when making that decision)
To answer your question about the processor in short
you said the E7500 was compatable.. does that make the E7400 compatable too?
yes, your motherboards specs that I gave you the link to specifically say that any 7xxx series Wolfdale Processor will work. So you know, they have a 1066 FSB which is pretty fast, not to mention it has 2 cores, so its like 2 processors in one, those processors aren't too much under what I'm going to use for my new build I'm working out right now. (I'm using the E8400.) The 7400 is a nice processor, and you should be very happy with it, IT IS THE HIGHEST YOUR BOARD SUPPORTS since you can't get the 7500.
XCLIO Godspeed Cases is a Micro ATX motherboard compatible Case so you are good to go there. I actually have looked at this case for myself before, and I like it. I would think a case like this would have plenty of room for a graphics card too.
To answer your question about the cooling,
if this is a decent case (will i need extra cooling?)
Not really, your PSU will probably have a fan that blows air out the back, and this case that I have linked to which I believe is the same you are talking about has 2 80mm top fans (heat rises, so thats good) and 2 180mm side fans (which you can have blow are directly onto the motherboard and graphics card, or have them blow hot air out) that is controversial, I prefer side fans to blow onto the motherboard, not out. Your cooling should be pretty good to go, you may want to add a fan in the back if you look at the pictures, that will blow hot air out(YOU HAVE TO GET THE HOT AIR OUT) Furthermore,
this case will have tons of extra cooling compared to the standard one you have now, so you are ok9600 GT's This is a good graphics card too, at one time it used to be one of the best, and that wasn't that long ago. However, is the card your looking at 1gb or 512mb or what? Generally speaking, the things to look at is the mb's or gb's, the bits i.e 128bit or 256bit and how many stream processors, i.e. 64, 128, etc. On all of these categories, and many other ones for graphics cards, the higher the numbers the bettter. So for example, a 1gb 256bit card that has 64 stream processors is much better than the one that is 512mb 128bit with 64 stream processors. So, you may want to look at that. Ordering from newegg.com can be pretty fast, and you get exactly what you want. Or any other online store really. Newegg is the best in my opinion. Not sure how it is with Australia and all though.
The 9800GTX is better, sorry if I give long answers. Just trying to be thorough.
PSU... I don't like either one of them because I never have heard of them and they are not on the list I provided below at the very bottom, notice the legend for what is good and what is not. Even that Athena one I would consider bad now that I have looked at the list. Your case should fit a ATX or Micro ATX, which ATX is better, more common. Has the same screw holes to mount but it is bigger, but if you are getting a bigger case that will be OK. I strongly suggest you buy at least the power supply from on line, or another store that has a name brand one, Corsair, Antec, SeaSonic, CoolerMaster. If you don't have a stong enough PSU, then your computer may not boot and in some cases it will actually blow and ruin other parts if not all in your computer if it is not strong enough.
With that said, make sure the PSU is what you have in the case,(not your old one) when you try to fire up with the new processor because that is 30 Watts higher than your original processor, same with your graphics card.
By the way, the 9600 GT's I have looked at online still require about a 450 Watt PSU, that hasn't changed.
and also is the 9600GT any good or would i be wasting money and should go for the 9800GTX?
I would buy everything online as there is more of a selection and you get exactly what you want. If you can find out more information about the card like is it just a x16 or is it a x16 2.0? Also what is the mb or gb on it? Bits? 128bit, 256bit? etc.
You did the right thing by now buying anything yet, be patient, this will be better for you.
I know this is a lot of information, be sure to re read where you feel necessary. I have provided several links and documentation for you to make a good decision, but it would be good to clear things through me on here first before you buy anything.
