Why not just add another 4 drive enclosure?
Are you using PM enclosures now? your controller will support PM?
The cases are identical to some of my older SCSI cabinets, so I would expect it to be as loud and efficient.
They have a cheaper case with one channel and 5 drives (I leave out the center for ventilation and reduce more heat).
OWC carries it, I'd ask them.

It depends on your RAID controller, which use to mean 3-4 drives per channel, but with most of today's drives that hit 90-110MB/sec (WD Caviar 640 or 1TB) 3 drives per channel is probably a better number. If you have older drives and say 500GB models, might be okay to use 4.

I was about to buy either a pair of 5-drive or the 8 (too tall to fit where I want) to simplify and consolidate.

10.5.2 'broke' and changed how external drives mount and communicate. Sonnet updated their firmware and driver for their Tempo PM controllers, and I wouldn't worry that it won't work with 10.5.5 unless you hear - otherwise I think AMUG, Firmtek, Sonnet, and others would be pointing it out in their reviews.
