get me wrong, it's just knowing when and where.
Now the problem I have with your approach under the OP's
requirements is the only way to fit that kinda storage over that long a
period is with external enclosures and there isn't many systems that
have external 4 lane serial storage
connectors builtin, so one needs a card that can perform that and if
you are shopping for a card to do that
then you might as well get one for a few $100 more that has on board
RAID. Also if the OP wanted to switch
distro's he will not have to worry about losing the RAID configuration
or hosing it in the process.
I've never had any problems with linux losing track of md based raid
mirrors or LVM configurations, and they import quite nicely into new
systems.
I'd consider using a SAS card on the host (LSI Logic makes some nice
ones), and each SAS port can drive 16 SATA drives on SATA/SAS backplane
multiplexors.

I'd start with a 3U 16 bay /server/ using a SAS/SATA backplane, too,
then when that fills up, add 16 drive expansion bays as needed...
something like http://www.aicipc.com/ProductImage.aspx?ref=RSC-3ED2-2
(but, by all means, pick your favorite chassis or system vendor)
