Just ordered the following items. Was this a good setup?

Hello! Im new to the boards and want to say hello!

I just ordered this system for ncix. Please let me know if i made a good decision...
Also I will probably need to get anew HSF that's quiet and performs well, if someone may recommend something.
(i have a radeon 9800 pro waiting to be used)

Will it have a good overclock potential?
