Well Paul, You seems to want to add a lot of building blocks... I myself am planning a structure with a single tower case (could be racked in 4U) with a 3ware Escalade 7500-12 which is capable of making a 12 Disk RAID5 volume. I'll probably do a 10x drives, 1x parity and 1x hotspare using 160Gb or 200Gb disk. (The OS is on a mirrored SCSI disk). But when I start I'll probably only get 5 disk, and add disks to the system as my need grow. This is where the LVM will help me expand the LVs. I decided not to use ReiserFS, but I'm still pondering between Ext3 or SGI's XFS. As the data on the Logical Volume will be large media files. On a side note, the 3ware Escalade supports spin-up controls for disk supporting it (only IBM drives have it). So you can slowly start a system without blowing the power supply.
