Building New Sound PC

Ok, well I'm building a computer for a friend that will mainly be used for radio quality sound podcasting. He has given me some requirements and I think I have a vague idea of what he needs.

He says he wants 3 hard drives one for the operating system, one for storage, and one for applications. He wants to run these in a raid format, and I'm not sure what Raid would be best for this. Two need to be 1 terabyte 7200 RPM drives, but I thought the OS one might benefit from a smaller Raptor, any opinions?

He also wants 4 Gigs of RAM, which should be easy enough to fulfill.

Now we're entering the area where I'm really confused the sound card and motherboard. He said he would like a Creative sound card with XLR, SPDIF,RCA, 1/4 in., and two other sound things I can't read. He also said something about mini toslink cables, which I'm confused about. He want the motherboard itself to have two firewire ports, though if necessary I can just get a firewire card, and as many USB ports as possible.

Now I'm not sure how much all this will cost, theres no strong need for video so that should cut some costs. I was thinking maybe the new AMD 790G motherboard would be a good fit for the build, but not sure about that. The budget is between 1-2k, but cheaper is better.

Any help would be appreciated.

The Gigabyte 780G MB, (GIGABYTE GA-MA78GM-S2H AM2+/AM2 AMD 780G HDMI Micro ATX AMD Motherboard), is good and has the features you want. However, it is AM2+/AM2 not Intel 775 CPU socket.
For Q6600/MB with intergrated graphics, ASUS P5E-VM HDMI LGA 775 Intel G35 HDMI Micro ATX Intel Motherboard.
The PSU you picked out is the right one for your app.
Someone elso will have to lead you the right way for a sound card.

Bump, any help?
