I'm so tired of researching this new system that I want to build.....Can someone please tell me if this computer will work for what I want to do ?

I want to run Sonar 5 and Kontakt 2 in this computer.....I will have one IDE HD for the XP Pro and my applications....I will have an SATA HD for vocals, and 2 other SATA HD's ( not sure about Raid0 yet ) for samples......The Soundcard will be an RME HDSP 9652......How much ram should I load and please tell me if this motherboard will work ? ......Thanks, Jim
