I have 6x160GB in a RAID. I use the PCI/IDE cards from Dick Smith (yep,
$56 including two cables - and they do see the full 160GB). You will
also need the latest IDE patch.

The main problem is that the PCI slots get awfully busy (AGP video,
NIC, 3xIDE). The IDE card with the sockets are just a bit too wide. I
how you fit 4 of these PCI cards.

I run XFS over software RAID5. I do not care much for speed (this is
for backups). For speed you will want faster PCI (64/66), properly
The 3ware 7500-8 will probably do a good job here but will add some
AU$1550 at cougar - almost the cost of 3 disks. US$500-550 in many US
