Sorry, but multi-TB I mean starting with something like 24TB and expanding out to ~100. I was planning to build a FreeNAS box for this using a 4U 24-bay case which requires ~3 PCIe slots. >> So thanks, all.

Do you have a reference for these USB sound dongles (that are also supported by Linux/ARM)? I've not found anything that inexpensive. I also wonder how hard it will be to build Shairport? I suspect there isn't already an RPM for it. *ponders actually signing up again for a fedora account to donate the SPEC if I have to write one* > Gordan -derek -- Derek Atkins, SB '93 MIT EE, SM '95 MIT Media Laboratory Member, MIT Student Information Processing Board (SIPB) URL: http://web.mit.edu/warlord/ PP-ASEL-IA N1NWH warlord@xxxxxxx PGP key available _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
