did you not see my page one post?
highlights:
32 2.5GHZ Opteron cores
128GB of RAM in 16 channels
27 DSPs dedicated to audio for up to 192 independent tracks of audio
if we need more storage we'll just grab a pair of Magma boxes, one for the PT setup (yeah you could buy the Digidesign branded ones I guess), and one for a slew of RAID controllers to connect to a few backplane boxes (with whatever, 20TB a piece in them)
can I ask, why FX 5800? it'll be idling 99% of the time
just grab an NVS and use that for your multi-head
I guess I did miss that in your post, and when I selected those parts, for some reason I kept thinking this was for a video workstation, not audio. Honestly with no budget I'd just go with a Pro Tools setup and be done.
