Hey Rodney, glad to hear you're upgrading your rig!
Anyway, here's an idea for a case:
http://otvtech.com/catalogue.html?page=shop.product_details&flypage=flypage_stock.tpl&product_id=4917&category_id=757It offers terrific cooling options at an affordable price point. It's also from a great company, so you know name-brands are good.
Your CPU choice is great - I've heard / read a lot of good things about the i5-760.
For the RAM, I've heard good things about Patriot. High-performance brand RAM, like Corsair or OCZ Gold or whatever is real important if you plan to do any over clocking. If not, then it's merely a matter of seeing whether or not the RAM is compatible with the board. Generally, if the RAM you're looking at has a speed supported by the board, it'll work.
That being said, it's always a good idea to wander over to the board's website to see if you can find a RAM-compatibility list.
4GB of 1333Mhz speed DDR3 RAM should be fine for whatever you're planning to use your computer for (I'm guessing mostly play GE:S
)
As namajnaG mentioned, you can always add more RAM later on if your needs change.
I definitely agree w/ Major on the board. Those slots are a bit close to comfort. You may want to think about doing a little bit more shopping around. As an example, here is a cheaper board with more breathing room:
