What do I need for OC'ing? (System Rebuild)

[Jitsu]

I'm currently semi-rebuliding my system, and I'm wondering what I need to change to overclock.

What I have thats getting re-used::::
-Mobo: Gigabyte 7n400 Pro II
-HDD'S: 1x Seagate 7200RPM IDE "Stuff" drive.
-Ram.... one stick of regular corsair 512
-Processor: Amd Athalon XP 2700+ Barton Core



What I'm thinking about purchasing::::
- HDD's:
1x WD Raptor 37gb 10,000 RPM SATA... For the system drive
1x WD 250gb 7,200 RPM SATA.............. For "Stuff"
- Case: Chieftec SOHO Case (Large and has 5 fan slots - keep stuff cool)
- Ram? (What is the faster ram used for, I'm guessing it can "Grab" Stuff quicker?)
- New CPU heatsink/fan
- A good (according to reviews) 500w+ Power Supply
- A rheostat for the case fans, and the cpu fan (So I can sleep at night)

Hows that sound?

Make sure to get a quality heatsink if you are overclocking. As for the other components, they shouldn't affect your overclock much except for the ram. Any new ram you get should be at least the same speed as your old ram, but there is no need to make it faster than your old ram. All your ram will run the speed of the slowest stick.

Zalman and Thermalright make good heatsinks, Swiftech, AVC, and Alpha are also good brands.
