It's a home server and the storage is near-line photo archives (I'm a
professional photographer) that's also backed up on REV cartridges.  I
don't need the performance of a multi thousand dollar server box just
the storage capacity to host up to a terabyte of images.  If I really
needed the performace I'd build somthing with SCSI or SATA drives but I
just need capacity.

Currently the box has:

IDE 80 GB main disk (root usr var tmp swap )
1x250GB FW 400 - scratch storage
2x300GB FW 400 in a gstripe set - storage for BackupPC which covers the
desktop boxes.
2x500GB FW 800 (on a separate FW800 controller) - this is going to be
the photo archive in a gvinum mirror set.
Then I have 4xUSB250GB drives that are not really doing anyting right
now and I may build into a RAID5 for future expansion.
