You can purchase a whole new dual opteron  740,    with 6 gigs of ram, a 
case to match and 6   74 gig  ultra320 sca drives  for about   $7k

I know because that's what I bought one for 2 weeks ago.   Using Tyan's  
dual board.

If you need some details and are willing to go that route,  let me know 
and I'll get you the information.
