Nice system! but its all wrong for an audio workstation.
R - What you should look for:- good processor(reduces latency), big cache, hyperthreading, quiet case/psu/cooling, SATA 3, PCIE-3 if using internal soundcard, for external audio interface Firewire 3200/USB3. What you don't need:- gfx card, high wattage psu, .
I am going to suggest qualities you should be looking for in parts and a couple of parts for each component instead of listing a specific build.
Need a quiet psu and case because you are going to be producing music, loud computers are irritating and interfering. Anything that produces less than 20 db should be fine but nothing more than 40db , just for reference 20db is like a quiet whisper and 40 like background music. You don't need a high wattage PSU so case and psu just need to be silent. You can try and save some money here.
eg of quiet cases: Antec sonata, Performance series. This website should be helpful http://www.silentpcreview.com/section9.html

If you are overclocking go with either the i5 2500k or the i7 2600k. I would go with the i7 2600k. Why? Hyperthreading, 2mb extra cache and higher turbo. Most digital audio suites , sequencers make full use of hyper threading it is easily worth the extra $100.
If you aren't overclocking go with the i5 2500/i7 2600.
Processor cooling:- Go with pre-build liquid loops like the corsair or antec ones for less noise.
Go with a Z68 mobo and save yourself from having to buy dedicated graphics card, because honestly you don't need one, also need the pcie bandwidth to be dedicated to the soundcard if you are using an internal one. Instead invest in a good soundcard. Try to look for a mobo with SATA3 PCI-E 3.
here is a list of Z68 mobos: http://www.newegg.com/Product/Produc...CE&PageSize=50
Asus, gigabyte and Asrock make good ones, and there is a spreadsheet on OCN detailing their specifications etc.
DDR 3 1600, atleast 6gb. The ripjaws X are good. I would get 8 gigs.
Win 7 64 bit.
Crucial M4 's or
or the spinpoint f3's
need something fast. This is fast and not as expensive as SSD.
Do you need monitor/keyboard/mouse?
Before we get to the audio parts, some questions to ask your friend. Does he need a DA/AD(digital to analog or analog to digital)converter? What kind of sound quality are you looking for? Does he already have mic, preamp, recorder, AD/DA converter, monitors, mixer, clock?How many tracks will he be recording at the same time? How many instruments will be connected at the same time? What he already has determines what he needs to add.What software does he use? Does he have a midi keyboard/controller? Also what monitor(sound monitor) does he have?Edited by exhaile - 10/18/11 at 4:43pm
